Book excerpt: After a brief discussion of our radar target identification program, we give a direct application of probability theory to the problem of deciding which of a set of possible targets is present. The reliability of discrimination depends on the noise level, the back ground hash, the variation of echo with target aspect angles, the energy and shape of the transmitted pulse, and the number of pulses. The effect of each of these variables is calculated and discussed, leading to some new conclusions about optimal radar design and optimal data processing. We think that the tactics which might succeed are quite different from those that have been tried in the past, and give elementary intuitive explanations why this is so.

Book Synopsis Complex Natural Resonances of Radar Targets Via Prony's Method by : C. W. Chuang
Download or read book Complex Natural Resonances of Radar Targets Via Prony's Method written by C. W. Chuang and published by . This book was released on 1975 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been shown that extraction of complex natural resonances and residues from exact transient responses via Prony's method is both efficient and accurate. However, in the art of radar interrogation the exact transient response is difficult to obtain and the authors must be content with an approximate one. Knowing the complex natural resonances of objects is essential to one type of radar target discrimination. In this paper the authors consider the use of Prony's method in extracting complex natural resonances from approximate backscattered ramp responses of radar targets. A ramp waveform is used in radar target discrimination because a good approximation to the time domain response can be obtained with only a few harmonically related frequency domain responses via Fourier synthesis. By applying Prony's method to this approximate ramp response, a few dominant resonances which are close to the origin of the complex frequency plane can be extracted. This is quite encouraging because for the purpose of radar target discrimination only a few dominant modes are needed. Objects considered are prolate spheroids, simple wire aircraft models and some realistic aircraft models. The accuracy of this method is found to be good when compared to the results obtained by other techniques.
Book Synopsis Resonances of Radar Targets and Target Discrimination by : Herbert Uberall
Download or read book Resonances of Radar Targets and Target Discrimination written by Herbert Uberall and published by . This book was released on 1980 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of the research program covers methods for target discrimination by radar scattering, making use of the natural resonances of the targets. The general plan of the program consists in a study of resonances of targets of simple shape (e.g., sphere) but complex composition (e.g., dielectric coating of conductors) during the first year, followed by simple conducting targets and comparison with parallel measurements performed at NSWC Dahlgren in the second year, with further extension to conductors of more complex shapes, using Waterman's methods, later on. The emphasis of our study is two-fold, namely: (1) to study ways how the resonance structure of the radar echo can be used for identifying the nature of the target (the 'inverse scattering problem'); and (2) to obtain a physical understanding of the phenomena that cause the resonances, and how they manifest themselves in both steady-state and pulsed echoes. Such an understanding, in preference to a more mechanical use of the singularity expansion method, will provide us with the true capability of mastering the target discrimination problem.
Book Synopsis Complex Natural Resonances of an Object in Detection and Discrimination by : Richard K. Mains
Download or read book Complex Natural Resonances of an Object in Detection and Discrimination written by Richard K. Mains and published by . This book was released on 1974 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report extends and formalizes the concept of using the complex natural resonances of objects as a tool in radar target discrimination. The complex natural resonances which characterize an object are found to be excitation invariant; i.e., the positions of the resonances in the complex frequency plane do not shift as the object is viewed along different incident directions or with different polarizations, which permit a minimum amount of data to be used in object discrimination. Once the dominant (low frequency or long time) natural resonances have been obtained for those objects of interest, a predictor-correlator type of processing can be applied to multi-frequency radar scattering data from an unknown target. It can be established from which of the known objects the scattering most likely originated. This done on the basis of correlations among the scattering and the various sets of natural resonances; the set of natural resonances showing the highest correlation identifies the most probable target.
Book Synopsis Radar Target Discrimination and Identification Using Extinction-Pulses and Single-Mode Extraction Pulses by :
Download or read book Radar Target Discrimination and Identification Using Extinction-Pulses and Single-Mode Extraction Pulses written by and published by . This book was released on 1991 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research program is to develop an efficient new radar target discrimination and identification scheme based on the natural frequencies of the target. It consists of synthesizing aspect-independent discriminant signals including Extinction-pulse (E-pulses) and Single-mode extraction pulses (S-pulses) which, when convolved numerically with late-time transient response of an expected target, lead to zero or single-mode responses. When the synthesized discriminant signals for an expected target are convolved with the radar return from a different target, the resulting signals will be significantly different from the expected zero or single-mode responses, thus, the differing targets can be discriminated. Major achievements on various topics under this research program are described in this report.
Book Synopsis Radar Target Detection by : Daniel Meyers
Download or read book Radar Target Detection written by Daniel Meyers and published by Elsevier. This book was released on 2012-12-02 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar Target Detection: Handbook of Theory and Practice covers a set of graphical solutions to the detection problem, designated as Meyer Plots, for radar systems design. A radar system's major purpose is the detection and location of an object by means of a return signal, which could be either a reflection or a beacon. This book is composed of four chapters. Chapter 1 presents the basic radar range equation, which is the basic relationship which permits the calculation of echo signal strength from measurable or known parameters of the radar transmitter, antenna, propagation path, and target. Chapter 2 provides examples for determining statistical signal detection using Meyer Plots, particularly for determining detection probability and integration loss and efficiency. Chapter 3 describes the application of target models to determination of detection probability. Chapter 4 examines how Meyer Plots can be used to solve problems involving most any target model.
