Book excerpt: "This thesis introduces novel signal processing algorithms for cognitive radar systems that consider the constraints of operation under real scenarios as well as hardware limitations. Specifically, the thesis focuses on the analysis and practical solution of three key problems encountered in the design and realization of the signal processing chain within the cognitive new-generation radars. Firstly, we consider detecting and excluding the non-homogeneous received data from the estimation of the interference covariance matrix. The available non-homogeneity detectors (NHDs) in the literature require estimating the covariance matrix for each examined data cell, leading to exacerbating the NHD complexity, especially with large-dimensional data. Instead, we employ the projection depth functions, inherited from the field of robust statistics, to formulate a new NHD test statistic that avoids estimating the covariance matrix. Moreover, the projection depth function converts the multivariate problem to a scalar one, evading the exponential growth of the computational complexity with the data dimension.\par Secondly, we turn our attention to a scarcely but nevertheless important discussed aspect of radar system, namely the waveform design for cognitive multi-input multi-output (MIMO) radars taking into account the reflective properties of the transmitting antenna array. For the first time, we propose a waveform design method using proximal optimization that not only improves the signal-to-interference plus noise ratio (SINR), but also lowers the reflected power from the transmitting antenna array. Consequently, the proposed waveform design method increases the radar system efficiency and protects the amplification unit of the transmitter, while at the same time, significantly improves the SINR. Finally, we introduce a novel formulation of the target frequency response (TFR) estimation problem, a crucial requirement for cognitive radars. Under the conventional assumption of a linear Gaussian model, the TFR is usually estimated using the Kalman filter. Surprisingly, even though in practice this assumption is often violated and the Kalman filter is no longer an optimal solution, the study of TFR estimation for more general models has not yet been considered. In our proposed formulation, the infinite hidden Markov model (iHMM) is used in TFR estimation without prior knowledge of the channel or the interference. Interestingly, when iterated over multiple pulses and under jamming conditions, the proposed estimation method exhibits superior performance compared to the Kalman and particle filters for different TFR models. Throughout the thesis, the newly proposed algorithms are evaluated by objective Monte Carlo simulations with different clutter distributions and radar parameters. Under the considered evaluation conditions, the results clearly show that the proposed methods can provide superior performance to existing benchmarks from the literature"--

Available in PDF, EPUB and Kindle. Book excerpt: Advances in digital signal processing algorithms and computer technology have combined to produce real-time systems with capabilities far beyond those of just few years ago. Nonlinear, adaptive methods for signal processing have emerged to provide better array gain performance, however, they lack the robustness of conventional algorithms. The challenge remains to develop a concept that exploits the advantages of both-a scheme that integrates these methods in practical, real-time systems. The Advanced Signal Processing Handbook helps you meet that challenge. Beyond offering an outstanding introduction to the principles and applications of advanced signal processing, it develops a generic processing structure that takes advantage of the similarities that exist among radar, sonar, and medical imaging systems and integrates conventional and nonlinear processing schemes.

Download or read book Signal Design for Modern Radar Systems written by Mohammad Alaee-Kerahroodi and published by Artech House. This book was released on 2022-11-30 with total page 379 pages. 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: Cognitive dynamic systems are inspired by the computational capability of the brain and the viewpoint that cognition is a supreme form of computation. The key idea behind this new paradigm is to mimic the human brain as well as that of other mammals with echolocation capabilities which continuously learn and react to stimulations according to four basic processes: perception-action cycle, memory, attention, and intelligence. The Impact of Cognition on Radar Technology is an essential exploration of the application of cognitive concepts in the development of modern phased array radar systems for surveillance. It starts by asking whether our current radar systems already have cognitive capabilities and then discusses topics including: mimicking the visual brain; applications to CFAR detection and receiver adaptation; cognitive radar waveform design for spectral compatibility; cognitive optimization of the transmitter-receiver pair; theory and application of cognitive control; cognition in radar target tracking; anticipative target tracking; cognition in MIMO radar, electronic warfare, and synthetic aperture radar. The book concludes with a cross-disciplinary review of cognition studies with potential lessons for radar systems.
