Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Special Issue is to gather recent advances and development in target tracking techniques to determine how they can be adapted for modern radar and sonar systems. After peer review, 17 articles in related areas have been accepted for publishing in this Special Issue. The published articles cover a range of topics and applications central to target tracking. There are eight papers about general multi-target tracking, including the topics of joint tracking and classification [3], adaptive estimation using clutter measurement probability [6], joint localization and tracking [7], extended target tracking [8], tracking with smoothing [11], DOA tracking [12], tracking under low detection probability [14], and sonar tracking and interception [17]. Three papers address multi-sensor multi-target tracking methods. Specifically, a multi-target estimating method for pulsed radar systems is proposed in [2], a joint dwell time and bandwidth optimization method in a radar network is proposed in [4], a and multiple marine ship tracking method with unknown backgrounds is presented in [9]. There are 2 papers [10,15] on the problem of target assignment in multi-sensor multi-target tracking. Moreover, Mallick et al. considered measures of nonlinearity of a polynomial curve in two dimensions [1], Zhao et al. explored the use of calibration targets for which the positions are known to the MPR system, to counter the loss in target localization accuracy arising from transmitter/receiver position errors [13], and Li et al. proposed an algorithm to apply the frequency diversity technique to passive azimuth estimation in [16].

Download or read book Demonstration of Advanced Techniques for Multi radar Target Tracking written by and published by . This book was released on 1993 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a demonstration system for combining track information from a number of radar sites. The information is used to form system tracks for the entire area surveyed by the radars, and the target positions and velocities are displayed graphically using earth centered coordinates. The site tracking program is a track-while-scan system that uses a relatively simple algorithm to associate observations with tracks. The system tracker uses the Dempster-Shafer method of data fusion to assign probabilities of association between site tracks and system tracks. Track updating is performed using a Kalman filter. The system tracker was tested using both the Dempster-Shafer method and a Bayesian approach. The system tracker also includes an initial attempt at correcting biases in the site radars. The report also studies the application of a neural network to the traveling salesman problem, a problem related to that of associating data to tracks.

Book excerpt: Tactical Persistent Surveillance Radar with Applications introduces technologists to the essential elements of persistent surveillance of tactical targets from both a hardware and software point of view, using simple Mathcad, Excel and Basic examples with real data. It is based on the type of surveillance done by drones like Scan Eagle, Predator, Reaper, Global Hawk, and manned aircraft like U-2, ASTOR, and JSTARS as well as spacecraft. The general topic is cellphone and datalink intercept, ground moving target radar, synthetic aperture radar, navigation, tracking, electronic scanning and cueing electro-optical sensors for activity based surveillance. Examples are taken from a wide range of technologies and techniques including passive detection, radar detection, antenna monopulse, active electronic scanned antennas (AESA), moving target tracking (MTT), motion compensation, tactical target spectral characteristics, moving target detection (MTI), space time adaptive processing (STAP), synthetic aperture radar (SAR) imaging, change detection (CCD), and synthetic monopulse.

Download or read book Advanced Signal Processing Handbook written by Stergios Stergiopoulos and published by CRC Press. This book was released on 2017-09-08 with total page 752 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Modern radar imaging requires advanced Synthetic Aperture Radar (SAR) techniques in order to compensate for the low resolution typically found on airborne radars. However, the techniques used to process the data collected during SAR operation require a great deal of computation. This paper proposes a novel efficient algorithm and approach to processing the data collected to quickly get high-resolution approximations for the locations of non-moving targets.

Download or read book Target Tracking Via Marine Radar written by Nishatha Nagarajan and published by . This book was released on 2012 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing energy needs have eventually increased the development of wind turbines. The constructions of wind turbines have several potential impacts of which the most significant factor is the increasing bird mortality rates due to collision and habitat loss. Since then, radars have been deployed to study the behavior of birds towards wind turbines. Radars employ target tracking for identifying the targets (birds) accurately and efficiently. Several methods of tracking were developed to improve the tracking efficiency of the radars over the years. Most widely used tracking techniques are Kalman filter and particle filter. These filters use data with random errors and estimate accurate values for the current state of the system. Kalman filter is a linear estimator which does not depend on a set of past observations and hence efficient in real time applications. The particle filter also known as sequential Monte Carlo method is a nonlinear estimator which uses a set of particles with various weights for estimation. However, particle filters have high computation time. Kalman and particle filters were developed over the years creating various models for various types of systems. A block version of Compressive Matching Pursuit (CoSaMP) algorithm used in signal reconstruction called BCoSaMP was employed in tracking. It was seen to give a similar or better performance than particle filter with less computation time. The BCoSaMP algorithm with Kalman filter estimation was developed which reduces the mean square error as compared to other models in certain cases. This thesis focuses on developing tracker models in radR. Kalman filter tracking model based on linear data and Gaussian noise that operates over a variety of target motions and velocities is developed. Particle filter is designed for nonlinear target motion with non-Gaussian noise. BCoSaMP model that assumes data as sparse is applied for target tracking and a modified BCoSaMP which replaces least square estimation with Kalman filter estimation are also implemented. These models were tested with different data sets and a comparative analysis is performed. The algorithms are tested on simulated data and marine radar data in radR to compare the effects of the developed tracker models with the conventional methods in radR. The hybrid algorithm is shown to have better performance over the other models in the case of simulated track for some targets. Particle filter has the highest detection rate with marine radar data.
