Book Synopsis Identification of Radar Targets by Pattern Recognition by : William Bernard Goggins
Download or read book Identification of Radar Targets by Pattern Recognition written by William Bernard Goggins and published by . This book was released on 1973 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of identifying radar targets without predetermined knowledge or measurements of their aspect angle is examined. The proposed solution is to use radar magnitude and phase versus frequency data in the resonance region as input data for pattern recognition techniques. Practical methods are developed for measuring radar phase and dealing with polarization effects. Pattern recognition algorithms that optimize separation between pairs of input data are developed. These algorithms are based on digital spatial frequency filtering of curves of the radar return versus the radar frequency. The technique is simulated on a digital computer for three objects - a cylinder, a cone, and a step cylinder - all of about the same size. Results show that at most aspect angles, satisfactory recognition is attained at moderate signal-to-noise ratios.

This book was released on 1998 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses a number of topics associated with microwave scattering from conducting objects such as Radar Cross Section (RCS) measurements, Inverse Synthetic Aperture Radar (ISAR) image reconstruction and their applications to radar target identification. An overview of experimental techniques for RCS determination and theoretical analysis of several standard scatterers used in RCS measurements is presented. An efficient deconvolution technique based on Singular Value Decomposition (SVD) is implemented to be used in measured data analysis. A number of experimental results are obtained from the facilities available in the UWO Electromagnetic Wave Laboratory and compared to the theoretical results. Different ISAR image reconstruction algorithms are formulated, implemented and tested on both simulated and measured data. A new target identification technique based on joint Physical Optics (PO) and Finite Difference Time Domain (FDTD) representations of the scattered response is introduced. The application of wavelets in ISAR is a new research direction and another contribution of this thesis is the best wavelet evaluation for data compression and denoising in target identification.

Book Synopsis High-Precision Automotive Radar Target Simulation by : Diewald, Axel
Download or read book High-Precision Automotive Radar Target Simulation written by Diewald, Axel and published by KIT Scientific Publishing. This book was released on 2023-08-15 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar target simulators (RTSs) deceive a radar under test (RuT) by creating an artificial environment consisting of virtual radar targets. In this work, new techniques are presented that overcome the rasterization deficiency of current RTS systems and enable the generation of virtual targets at arbitrary high-precision positions. This allows for continuous movement of the targets and thus a more credible simulation environment.

Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the optimization of both single and full polarization radar transmission waveforms to maximize target identification discrimination. This theory is applied to the discrimination of the T-72 and M1 battle tanks based upon simulated target frequency response data. Significant performance improvement in identification is obtained using an optimized transmission waveform over that of a standard chirped pulse.

Book Synopsis Automatic Target Detection And Recognition: A Wavelet Based Approach by :
Download or read book Automatic Target Detection And Recognition: A Wavelet Based Approach written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wavelet based target detection and identification algorithms for radar applications are presented and tested and evaluated on computer simulated data. The algorithms make use of a scale sequential and/or scale recursive paradigm where computations are performed within and across scales in a multiresolution analysis (MRA) of the sensor data relative to a compactly supported discrete orthonormal wavelet basis. It is argued that such procedures are computationally efficient and offer promise of yielding near optimal performance with a minimum CPU time burden. Specific applications considered in the report include automatic target identification from high range resolution radar (HRR), target detection in the presence of fractal noise and the integration of multisensor data in the tracking of aircraft. Other applications addressed include scale recursive optimal filtering and the synthesis of parallel architectures for the 1-D discrete wavelet transform. The report includes a full discussion of the theory behind the various detection and identification algorithms plus results from Monte Carlo simulations.

Book Synopsis Marcum's and Swerling's Data on Target Detection by a Pulsed Radar by : L. F. Fehlmer
Download or read book Marcum's and Swerling's Data on Target Detection by a Pulsed Radar written by L. F. Fehlmer and published by . This book was released on 1962 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marcum has produced a definitive treatment of the statistical problem of target detection by a pulse radar. The text and graphs of Marcum's papers are presented in terms so highly mathematical that his results may not appear as useful as they really are. The purpose of this memo is to describe the problem that Marcum solved and to present graphs of more extensive and more accurate computed data in a form which may prove more useful for most applications. Nothing new is added from the statistical viewpoint. Those interested in the mathematical development are referred to Studies of Target Detection by Pulsed Radar, IRE Transactions Volume IT-6, No. 2, April 1960.

Book Synopsis Adaptive Threshold Logic for Identification of Simulated Radar Targets by : A. Timothy Ewald
Download or read book Adaptive Threshold Logic for Identification of Simulated Radar Targets written by A. Timothy Ewald and published by . This book was released on 1965 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of adaptive threshold logic is considered as a means of establishing simple data transforms that will permit the automatic classification of patterns whose signal properties are too complex to be amenable to explicit analytic description. In an attempt to study the learning characteristics of adaptive logic systems, monopulse radar signal returns of multiple targets were computer-simulated to generate different classes of signal patterns. Three levels of pattern complexity were examined. Sum- and difference-transformed data patterns were learned more quickly than the ratio transform for one- and two-target patterns. The ratio transform was unsuccessful at the second level of complexity, i.e., the introduction of patterns of three targets one-quarter beamwidth apart versus one target. Difference-transform data produced weight learning plots that exhibited marked oscillation in early trials before converging to a solution. The sum transform showed oscillation in the learning plot similar to the two-target cases, but of no longer duration. At an S/N of 2, sum and difference transforms were successful in discriminating a two-target, one-quarter beamwidth apart pattern from a five-target, one-quarter beamwidth apart pattern, but exhibited a distribution of weighting functions suggesting that only the first and last few intervals of the radar scan provided useful information.
