This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In passive coherent locators (PCL) systems, noise and the precision of direction of arrival (DOA) estimation are key issues. This thesis addresses the implementation of sophisticated DOA estimation methods, in particular the multiple signal classification (MUSIC) algorithm, the conventional beam forming (CBF) algorithm, and the algebraic constant modulus algorithm (ACMA). The goal is to compare the ACMA to the MUSIC, and CBF algorithms for application to PCL. The results and analysis presented here support the use of constant modulus information, where available, as an important addition to DOA estimation. The ACMA offers many simple solutions to noise and separation related problems; at low SNR levels, it provides much more accurate estimates and yields reasonable separation performance even in the presence of challenging signals. Differential ACMA, which allows the simple digital removal of the direct signal component from the output of a sensor array, is also introduced.

Download or read book Direction of Arrival Estimation Technique for Narrow band Signals Based on Spatial Discrete Fourier Transform written by Ramin Zaeim and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deals with the further development of a method for Direction of Arrival (DOA) estimation based on the Discrete Fourier Transform (DFT) of the sensor array output. In the existing DFT-based algorithm, relatively high SNR is considered, and it is assumed that a large number of sensors are available. In this study an overview of some of the most commonly used DOA estimation techniques will be presented. Then the performance of the DFT method will be analyzed and compared with the performance of existing techniques. Two main objectives will be studied, firstly the reduction of the number of sensors and secondly the performance of the DFT based technique in the presence of noise. Experimental simulations will be presented to illustrate that in absence of noise, the proposed method is very fast and using just one snapshot is sufficient to accurately estimate DOAs. Also, in presence of noise, the method is still relatively fast and using a small number of snapshots, it can accurately estimate DOAs. The above mentioned properties are the result of taking an average of the peaks of the DFTs, X_n (k), obtained from a sequence of N_s snapshots. With N_s sufficiently large, the average over N_s snapshots approaches expected value. Also, the conditions that should be satisfied to avoid overlapping of main-lobes, and thus loosing the DOA of some signals, in the DFT spectrum are examined. This study further analyzes the performance of the proposed method as well as two other commonly used algorithms, MUSIC and conventional beamformer. An extensive simulation was conducted and different features of the spatial DFT technique, such as accuracy, resolution, sensitivity to noise, effect of multiple snapshots and the number of sensors were evaluated and compared with those of existing techniques. The simulations indicate that in most aspects the proposed spatial DFT algorithm outperforms the other techniques.

Download or read book Bistatic Radar written by Mikhail Cherniakov and published by Wiley. This book was released on 2007-04-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bistatic radars have been a focus of study since the earliest days of radar research. Despite this, until recently only a few bistatic systems have crossed the experimental study threshold, and, consequently there is little knowledge about them compared with their monostatic counterparts. Now, there is a fast growing interest in bistatic radar, due to its importance in the development of defence, remote sensing, aerospace, meteorological and navigation application fields, as well as its unique pecularities. These include covert operational ability relevant to the receiver position, counter-stealth ability, and a potentially reduced cost as one transmitter can be used to send information to several receivers. With contributions from international experts working with bistatic radar, this book provides an introduction to the technology, covering information on basic principles and design. Starting with a detailed look at monostatic radar, examining the development of the field as a whole, the book then goes on to: introduce the classical aspects of bistatic radar such as geometry, power budget and resolution; present an in depth analysis of bistatic scattering of electromagnetic waves; provide an overview of the bistatic radar potential which follows from their bistatic nature; discuss forward scattering radar; investigate forward scattering radar for air targets detection and tracking; set out an experimental study of real world forward scattering radar. Bistatic Radar: Principles and Practice gives an up-to-date overview of this important technology for practising engineers and researchers involved in the design and implementation of bistatic radar in a range of industries. It is also a valuable reference for advanced students taking special courses in radar technology.
