Available in PDF, EPUB and Kindle. Book excerpt: A novel radar technique is proposed for detecting the presence of a target having a priori known frequency-dependent scattering properties. The target coexists with a large collection of clutter elements having random scattering properties and ranges. Assuming a wideband random signal excitation, the power spectrum of the scattered field consists of the target return having an a priori known frequency behavior embedded in a clutter return having a random frequency dependence. On an ensemble average basis, the clutter appears as additive noise from which the existence of a prescribed target return must be extracted.

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.

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.

Download or read book Target Detection by Marine Radar written by John N. Briggs and published by IET. This book was released on 2004-12-03 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar is a legal necessity for the safe navigation of merchant ships, and within vessel traffic services is indispensable to the operation of major ports and harbours. Target Detection by Marine Radar concentrates solely on civil marine operations and explains how marine surveillance radars detect their targets. The book is fully illustrated and contains worked examples to help the reader understand the principles underlying radar operation and to quantify the importance of factors such as the technical features of specific equipment, the weather, target reflection properties, and the ability of the operator. The precision with which targets are positioned on the radar screen and with which their progress is tracked or predicted depends on how definitely they have been detected, therefore a whole chapter has been devoted to the issue of accuracy. The various international regulations governing marine radar are examined, a brief historical background is given to modern day practice and the book doses with a discussion of the ways in which marine radar may develop to meet future challenges.
Download or read book Principles of Modern Radar written by Jerry Eaves and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, Principles of Modern Radar, has as its genesis a Georgia Tech short course of the same title. This short course has been presented an nually at Georgia Tech since 1969, and a very comprehensive set of course notes has evolved during that seventeen year period. The 1986 edition of these notes ran to 22 chapters, and all of the authors involved, except Mr. Barrett, were full time members of the Georgia Tech research faculty. After considerable encouragement from various persons at the university and within the radar community, we undertook the task of editing the course notes for formal publication. The contents of the book that ensued tend to be practical in nature, since each contributing author is a practicing engineer or scientist and each was selected to write on a topic embraced by his area(s) of expertise. Prime examples are Chaps. 2, 5, and 10, which were authored by E. F. Knott, G. W. Ewell, and N. C. Currie, respectively. Each of these three researchers is rec ognized in the radar community as an expert in the technical area that his chap ter addresses, and each had already authored and published a major book on his subject. Several other contributing authors, including Dr. Bodnar, Mr. Bruder, Mr. Corriher, Dr. Reedy, Dr. Trebits, and Mr. Scheer, also have major book publications to their credit.

Download or read book Advanced Radar Detection and Processing Techniques for Low Electromagnetic Scattering Targets written by Lee A. Morgan and published by . This book was released on 1979 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar cross section measurements were made on Teledyne Micronetics' Radar Range using C-band one nanosecond pulses. The radar target was made up of retrodirective Luneberg lenses variously deployed on a turntable. The number of lenses varied from two to six. For each deployment of targets, the impulse response was experimentally determined with the help of a sampling scope and the complex conjugate of this impulse response was synthesized using power splitters and delay lines. This signal was then transmitted and the RCS enhancement was measured by reducing the level of the transmitted power until the maximum response was equal to a previously established reference level. Subsequently additional power splitters and delay lines were utilized to synthesize matched receiver response and a similar comparison technique was used to measure the increase in the RCS. The configurations which were tried included equal and unequal spacings and path geometries where the individual reflecting centers were separable and cases where they overlapped. The observed value of RCS enhancement were compared with the theoretical values and it was demonstrated that the agreement between the two values was in general well within one dB. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research program are to study the feasibility and to develop schemes for using an ultra-wideband or short-pulse (UWB/SP) radar to (1) detect a target in a sea clutter environment and (2) identify airborne targets. For the first topic, we have conducted a theoretical and experimental study of the transient scattering of a short pulse from sea surfaces of various models and the application of the E-pulse technique to detect a target flying above a disturbed sea surface. For the second topic, we have developed the schemes of target identification using the E-pulse technique, the neural network method, the time-domain imaging and some other related methods. This report summarizes many significant results which may be useful in the design of future UWB/SP radars.
