Book excerpt: Radarsensoren detektieren Objekte innerhalb eines Beobachtungsbereichs und messen die Entfernungen und Radialgeschwindigkeiten dieser sogenannten Ziele relativ zum Ort des Radars. Für die gleichzeitige, hochgenaue und eindeutige Messung von Entfernung und Radialgeschwindigkeit, auch in Mehrzielsituationen ist der Sendesignalentwurf ausschlaggebend. In der vorliegenden Arbeit werden zunächst die bereits etablierten Sendesignale für Dauerstrichradare erörtert, bevor auf dieser Basis Weiterentwicklungen dieser Sendesignale beschrieben und analysiert werden. Zusätzlich werden Detektionsverfahren beschrieben und für die Verwendung mit den neuen Sendesignalen weiterentwickelt. Radar sensors detect objects, so-called targets, within an observation area and measure range and radial velocity relative to the location of the radar. The simultaneous, highly accurate and unambiguous measurement of range and radial velocity even in multi target situations is a matter of the appropriate waveform design. This thesis describes and analyzes state of the art waveforms for continuous wave radar. Based on these waveforms new approaches and enhancements are presented. In addition to that, detection methods are discussed and improved for the use in combination with the new radar waveforms.

Available in PDF, EPUB and Kindle. Book excerpt: The range of a radar is a function of average transmitter power and is independent of the modulation waveform. It does not matter whether the transmitter operates in a pulsed or CW mode. In many applications, an average power of only a few watts is adequate. In these cases, CW operation can have a number of advantages. Solid state power sources can readily be utilized and a single RF source can serve as both transmitter and local oscillator. Another advantage is waveform flexibility. In a CW radar the waveform can be designed to perform a variety of functions, e.g., detect fixed and moving targets, determine sense of radial velocity and communicate with a target over a fade-free channel. This paper describes waveforms and design techniques that can be used to achieve the above mentioned functions with a CW radar. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book gives you a comprehensive overview of key optimization tools that can be used to design radar waveforms and adaptive signal processing strategies under practical constraints -- strategies such as power method-like iterations, coordinate descent, and majorization-minimization – that help you to meet the more and more stressing sensing system requirements. The book walks you through how radar waveform synthesis is obtained as the solution to a constrained optimization problem such as finite energy, unimodularity (or being constant-modulus), and finite or discrete-phase (potentially binary) alphabet, which are dictated by the practical limitations of the real systems. Several approaches in each of these broad frameworks are detailed and various applications of these optimization techniques are described. Focusing on a holistic approach rather than a problem-specific approach, the book shows you what you need to effectively formulate waveform design and understand the flexibility of the framework for adapting to your own specific needs. You’ll have full access to the tools and knowledge you need to design waveform with optimized correlation/cross-correlation properties for SISO/SIMO and MIMO radars, taking into account spectral constraints for cognitive rads, as well as coexistence with communications and mitigate possible Doppler and quantization errors, and more. The book also includes representative software codes that further help you generate the described solutions. With its unique style of covering mathematical results along with their applications from diverse areas, this is a much-needed, detailed handbook for industry researchers, scientists and designers including medical, marine, defense, and automotive companies.

Available in PDF, EPUB and Kindle. Book excerpt: The intent of this project was to design and simulate a frequency modulated continuous wave (FM-CW) radar system capable of making target range and velocity measurements. MATLAB was used to model each component of the FM-CW radar system and simulate transmit and receive signal behavior, channel effects, and target radar cross section (RCS) characteristics. A top-down approach to the design of the FM-CW radar system was presented beginning with an overview of theory and architecture followed by a detailed explanation of each component in the signal path. Key interactions between components were discussed as well as potential differences between real world components and their simulated counterparts. An overview of the signal processing techniques and software architecture required to make target range and velocity measurements was also presented and implemented. An overall FM-CW radar system simulation was implemented in MATLAB including simulated channel effects and targets. The simulation was run so that resultant target range and velocity measurements were obtained and radar system performance and simulation fidelity were evaluated and presented.

This book was released on 2010-04-04 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent innovations in modern radar for designing transmitted waveforms, coupled with new algorithms for adaptively selecting the waveform parameters at each time step, have resulted in improvements in tracking performance. Of particular interest are waveforms that can be mathematically designed to have reduced ambiguity function sidelobes, as their use can lead to an increase in the target state estimation accuracy. Moreover, adaptively positioning the sidelobes can reveal weak target returns by reducing interference from stronger targets. The manuscript provides an overview of recent advances in the design of multicarrier phase-coded waveforms based on Bjorck constant-amplitude zero-autocorrelation (CAZAC) sequences for use in an adaptive waveform selection scheme for mutliple target tracking. The adaptive waveform design is formulated using sequential Monte Carlo techniques that need to be matched to the high resolution measurements. The work will be of interest to both practitioners and researchers in radar as well as to researchers in other applications where high resolution measurements can have significant benefits.

Download or read book Tractable Radar Waveform Design Under Practical Constraints written by Omar Aldayel and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Waveform design is one of the central aspects of radar systems. It can determine many of the radar properties. A well-designed waveform can improve the signal-to-interference-plus-noise ratio (SINR), enable suitable delay (range) resolution, and utilize the spectrum efficiently. Moreover, for multiple array radar system, waveform diversity can be employed to enhance the flexibility of the transmit beampattern design and enable efficient management of radar radiation power in directions of interest.While unconstrained waveform design is straightforward, a key open challenge is to enforce some of the significant practical constraints of constant modulus, waveform similarity and spectral interference constraints. Incorporating these constraints in an analytically tractable manner is a longstanding open challenge. This is due to the fact that the optimization problem subject to these constraints is a hard non-convex problem. Decades of the past work have shown a stiff trade-off between analytical tractability (achieved by relaxations to manageable constraints) and realistic design that exactly obeys these practical constraints but is computationally troublesome. In this dissertation, we propose a new framework that breaks this classical trade-off.In the first part, we address the problem of a joint transmit waveform and receive filter design for radar systems under the important practical constraints of constant modulus and waveform similarity. We develop a new analytical approach that involves solving a sequence of convex Quadratically Constrained Quadratic Programing (QCQP) problems, which we prove converges to a sub-optimal solution. Because an improvement in SINR results via solving each problem in the sequence, we call the method Successive QCQP Refinement (SQR). We evaluate SQR against other candidate techniques with respect to SINR performance, beampattern and pulse compression properties in a variety of scenarios. Results show that SQR outperforms state of the art methods that also employ constant modulus and/or similarity constraints while being computationally less burdensome.In the second part, we address the problem of designing a beampattern for Multiple-Input-Multiple-Output (MIMO) radar, which in turn is determined by the transmit waveform. A new approach is proposed in our work, which involves solving the hard non-convex problem of beampattern design using a sequence of convex equality constrained Quadratic Programs (QP), each of which has a closed form solution. The converged solution achieves constant modulus and satisfies the KarushKuhnTucker (KKT) optimality conditions, which we prove formally is possible under realistic assumptions. We evaluate the proposed successive closed forms (SCF) algorithm against state-of-the-art MIMO beampattern design techniques and show that SCF breaks the trade-off between desirable performance and the associated computation cost. Furthermore, we address the problem of designing a beampattern for MIMO radar under a spectral interference constraint, which in turn is determined by the transmitted waveform, as well as the constant modulus constraint. One key challenge when jointly enforcing the spectral interference constraint and the constant modulus constraint is to ensure feasibility of the optimization problem. A new approach is proposed in our work, which also involves solving a sequence of constrained quadratic programs, each of which results in a closed form solution. We formally prove that feasible set of each QP problem in the proposed beampattern optimization under interference constraint and the constant modulus constraint (BIC) algorithm is always non-empty. We evaluate BIC algorithm against the state-of-the-art MIMO beampattern design techniques under the constant modulus constraint and show that BIC achieves a higher performance while maintaining a low spectral interference level in the desired bands.In the final part of this dissertation, we address the problem of radar ambiguity function shaping. Ambiguity function shaping continues to be one of the most challenging open problems in cognitive radar. Analytically, a complex quartic function should be optimized as a function of the radar waveform code. We develop a new approach called Adaptive Sequential Refinement (ASR) to suppress the clutter returns for a desired range-Doppler, i.e. ambiguity function response. ASR solves the aforementioned optimization problem in a unique iterative manner such that the formulation is updated depending on the iteration index. We establish formally that: 1.) the problem in each step of the iteration has a closed form solution, and 2.) monotonic decrease of the cost function until convergence is guaranteed. Experimental validation shows that ASR perform better than state of the art alternatives even as its computational burden is orders of magnitude lower.In summary, this dissertation develop a new sequence of convex problems approaches towards solving the hard non-convex problems that appear in practical radar waveform design. Finally, we present some ideas for future research which address waveform design for cooperative radar-communication systems optimization, MIMO ambiguity function shaping and waveform design for autonomous vehicle.
