Book Synopsis Signal Polarization Selection for Aircraft Radar Control by : Nikolay Kondratyevich Yurkov
Download or read book Signal Polarization Selection for Aircraft Radar Control written by Nikolay Kondratyevich Yurkov and published by Springer Nature. This book was released on 2021-03-30 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the synthesis of polarization selection system in the background of passive noise formed by reflections from space-distributed targets. This synthesis is fulfilled as close as possible to its ideal configuration in terms of maximal signal-to-noise ratio for the matched load of radar station antenna system. It presents a new approach to radar system resolution enhancement based on the development of mathematical model for radiometric receivers with mono-pulse antenna systems, as well as creation of a new algorithm that allows increasing angular resolution during the object’s search and tracking due to special signal processing.
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.

Book Synopsis Polarimetric Radar Imaging by : Jong-Sen Lee
Download or read book Polarimetric Radar Imaging written by Jong-Sen Lee and published by CRC Press. This book was released on 2017-12-19 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent launches of three fully polarimetric synthetic aperture radar (PolSAR) satellites have shown that polarimetric radar imaging can provide abundant data on the Earth’s environment, such as biomass and forest height estimation, snow cover mapping, glacier monitoring, and damage assessment. Written by two of the most recognized leaders in this field, Polarimetric Radar Imaging: From Basics to Applications presents polarimetric radar imaging and processing techniques and shows how to develop remote sensing applications using PolSAR imaging radar. The book provides a substantial and balanced introduction to the basic theory and advanced concepts of polarimetric scattering mechanisms, speckle statistics and speckle filtering, polarimetric information analysis and extraction techniques, and applications typical to radar polarimetric remote sensing. It explains the importance of wave polarization theory and the speckle phenomenon in the information retrieval problem of microwave imaging and inverse scattering. The authors demonstrate how to devise intelligent information extraction algorithms for remote sensing applications. They also describe more advanced polarimetric analysis techniques for polarimetric target decompositions, polarization orientation effects, polarimetric scattering modeling, speckle filtering, terrain and forest classification, manmade target analysis, and PolSAR interferometry. With sample PolSAR data sets and software available for download, this self-contained, hands-on book encourages you to analyze space-borne and airborne PolSAR and polarimetric interferometric SAR (Pol-InSAR) data and then develop applications using this data.
Book Synopsis Evaluation of System Identification Algorithms for Aspect-Independent Radar Target Classification by : Peter David Larison
Download or read book Evaluation of System Identification Algorithms for Aspect-Independent Radar Target Classification written by Peter David Larison and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A radar target, acting as a scatterer of an incident electromagnetic wave, can be considered as a linear time-invariant system. Previous work has shown that the target's pole locations are independent of the incident electromagnetic excitation, including incident wave shape, aspect and polarization. This thesis develops the Kumaresan-Tufts and Cadzow-Solomon signal processing algorithms into computer routines and evaluates their pole extraction performance. Data used to evaluate the extraction algorithms includes synthetic and integral equation generated signals with additive noise, in addition to measurements of scattering by scale models made in an anechoic chamber.

Book Synopsis Nonconventional Aspects of Radar Target Classification by Polarization Properties by : Karl H. Steinbach
Download or read book Nonconventional Aspects of Radar Target Classification by Polarization Properties written by Karl H. Steinbach and published by . This book was released on 1973 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manmade objects embedded in inhomogeneous media such as soils, building materials, and atmospheric layers may be detected by radar-like systems. The report reviews the system requirements and examines the role polarization phenomena can play in meeting these requirements. The scattering properties of potential targets and other disturbances in the medium as well as surface reflections and attenuation effects are taken into consideration. Rigorous equations describing the depolarized echo of radar reflectors as a function of their physical shape and the polarizational state of the incident wave are derived. The scattering theory of G. MIE is extended to include dissipative media and to permit the computation of the radar cross section of spheres for any combination of complex material constants. (Modified author abstract).

Basic Theory and Modeling of Polarimetric Clutter Phenomenology written by W. M. Boerner and published by . This book was released on 1988 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of our polarimetric research is to conduct a unified and cohesive investigation to answer the question: How can polarization properties of targets/background speckle be utilized either by themselves or in concert with other electromagnetic probing methods such as doppler, multispectral, pulse compression, etc., to best provide a basis for radar target classification, imaging, and identification? Scattering objects of interest include airborne/ground/marine targets of a large variety of sizes, shapes, and material decomposition and embedded in varied stationary/moving/fluctuating background scatter, which, we are confident, can most effectively be characterized via polarimetric radar/scatterometer methods including both coherent and partially coherent wave treatments. It is specific objective of this task to approach and to investigate the polarimetric radar clutter problem using a unique approach of a strongly interdigitalizing analytical, modeling, computer-numerical/graphical, and measurement interpretive nature. A basic theory for a model-independent clutter description which can be applied to any specific type of clutter without a priori knowledge of the clutter model, i.e., a model-independent clutter description, in theory, is introduced.

Download or read book Basic Concepts of Radar Polarimetry and Its Applications to Target Discrimination, Classification, Imaging and Identification written by and published by . This book was released on 1982 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: In meticulous detail, a succinct summary of basic electromagnetic wave polarization descriptors, of the various scatterer polarization transformation matrices, and its invariants of the associated optimal matrix polarizations, and of the scatterer descriptive operators is introduced. It is then shown how the five (5) independent matrix parameter for the relative phase mono-static scattering matrix describing an isolated, yet regionally distributed, target in a reciprocal propagation medium can be recovered from (1) amplitude-only, (2) mixed amplitude plus partial phase, (3) complete two-step amplitude-phase measurements. Basic properties of the radar scattering matrix for linear (H, V) and circular (R, L) polarization basis are described in terms of geometrical target features as functions of the specular point surface coordinate parameters, known as gaussian principal, main and related curvature functions. Based upon this succinct background introduction on radar polarimetry, the concepts are applied mainly for the coherent case to various classes of increasing order of sophistication, as defined in detail in the INTRODUCTION, to the problem of radar target handling for the non-cooperative, limited-data case.
