Book Synopsis Generation and Simulation of Clutter for RADAR Testing Using FPGA by : Pardhu Thottempudi
Download or read book Generation and Simulation of Clutter for RADAR Testing Using FPGA written by Pardhu Thottempudi and published by LAP Lambert Academic Publishing. This book was released on 2015-06-30 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detection of weak target echo in the presence of strong clutter is the main objective of any RADAR. To evaluate the performance of RADAR it is required to generate the clutter of various types including land and sea. This clutter is of non Gaussian distribution such as lognormal, Weibull and k-type. In this book it is proposed to develop a clutter generation algorithm of given distribution type. This process consists of random number generator with Gaussian distribution converting into a non Gaussian using ZMNL (Zero Memory Nonlinearity Transformation) technique. It also includes amplitude shaping and addition other interference signals.

Download or read book An IF (Intermediate Frequency) Clutter Signal Generator for the DREO EW (Electronic Warfare) Engagement Simulation Facility written by and published by . This book was released on 1986 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the implementation of an intermediate frequency (IF) radar clutter generator. The generator provides signals for the monopulse tracking radar which forms part of the Electronic Warfare Engagement Simulation Facility. Land clutter signals with log normal, Weibull and exponential spatial amplitude distributions are produced, as well as exponential sea clutter signals. Fluctuating clutter from wind blown scatters is modelled using narrowband amplitude modulation. Clutter induced angle tracking errors are also represented. The report describes the major clutter mechanisms relevant to noncoherent radars in low grazing angle scenarios. The hardware and equations used in modelling are described, and the report presents envelope detected waveforms plots and histograms. This work has applications in accurate modelling of radar performance in low altitude engagements. Keywords: Cross section; Exponential grazing angle; Intermediate frequency jamming; Land clutter; Missile seeker; Monopulse; Polarization; Sea clutter; Sea state; Tracking; Moving target indicators; Canada.

Download or read book High-Level Adaptive Signal Processing Architecture with Applications to Radar Non-Gaussian Clutter. Volume 3. Spherically Invariant Random Processes for Radar Clutter Modeling, Simulation, and Distribution Identification written by and published by . This book was released on 1995 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation is motivated by the problem of detection of weak signals in a strong radar clutter background. The fundamental issues that need to be addressed in the weak signal detection problem are radar clutter modeling, simulation and distribution approximation. These issues are easily addressed when the clutter is a correlated Gaussian random process. However, these issues have not received much attention when the clutter is a correlated non-Gaussian random process. This thesis addresses the problem of modeling, simulation and distribution approximation of correlated non-Gaussian radar clutter. The theory of spherically invariant random processes is used for statistical characterization of non-Gaussian radar clutter. Several examples of multivariate probability density functions arising from spherically invariant random processes are presented. A new result which uniquely characterizes the multivariate probability density functions arising from spherically invariant random processes is obtained. Two new canonical computer simulation procedures are developed in order to simulate radar clutter that can be described by spherically invariant random processes. Finally, a new algorithm is used to address the problem of distribution identification of the clutter using relatively small sample sizes. This technique makes use of the result which uniquely characterizes the multivariate probability density functions arising from spherically invariant random processes and reduces the multivariate distribution approximation problem to an equivalent univariate distribution approximation problem resulting in a major simplification of processing.
Book Synopsis An OTH Radar Clutter Simulation by :
Download or read book An OTH Radar Clutter Simulation written by and published by . This book was released on 1991 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer simulation is described which was developed with the objective of arriving at an understanding of OTH radar clutter originating in the equatorial ionosphere. This source of clutter is of particular interest in OTH radar, since all radar propagation paths must pass through the equatorial region, even if the desired targets are far removed from it. A central feature of the simulation is an ionospheric propagation model developed to synthesize OTH radar clutter by making use of state-of-the art models for global ionospheric structure, including small-scale irregularities, and combining these with efficient ray tracing procedures and a multiple phase-screen approach to computing the diffraction of radar energy by the irregular ionosphere. Simulated clutter data is compared to actual measurements using several radars, with generally satisfactory results.
Book Synopsis High Resolution Radar Clutter Analysis and Modeling for Advanced Target Detection Strategies by :
Download or read book High Resolution Radar Clutter Analysis and Modeling for Advanced Target Detection Strategies written by and published by . This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report results from a contract tasking University of Pisa as follows: The research is divided in two phases. In the first phase, we consider modeling and estimating the characteristic parameters of high resolution non-Gaussian sea clutter. We will investigate specifically nonstationarity and possible non-Gaussianity of the clutter on long period of time, by applying nonhomogeneity tests and spectral analysis to highlight the temporal changes of the clutter process. The analyses of high resolution clutter will be performed by processing complex clutter data collected in November 1993 and in winter 1998 with the high resolution IPIX radar, provided by McMaster University, at a range resolution of 60 m, 30 m, 15 m, 9 m, and 3 m, in like- (HH-VV) and crosspolarizations (HV-VH) An accurate characterization of the high resolution radar clutter allows a more adequate design of the radar detector of targets. This detector needs to be adaptive to the data and should have the ability to comply with the non-homogeneous nature of the clutter interference. This aspect of the problem will be discussed in the second phase of this study. A detailed analysis of the impact of the nonstationarity of the clutter will be performed first analytically (where possible) and by means of simulations; then we will use the real recorded data to feed adaptive detectors, designed for stationary Gaussian and non-Gaussian clutter, and we will compare theoretical and simulated performance with real data performance.

Download or read book A Clutter Model for Space Based Radar written by Carl J. Lauer and published by . This book was released on 1983 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clutter model for a pulse doppler space based radar simulation is described. Ground clutter is represented as a random process with mean power, mean doppler, and doppler spread determined from experimental measurements and from physical and geometrical quantities pertinent to the radar location, look angle, beam pattern, etc. The above three quantities are used to define the clutter spectrum observed at a given radar range gate, and a statistical signal generation technique is employed to generate a realization or sample of the instantaneous clutter signal observed.

Available in PDF, EPUB and Kindle. Book excerpt: The performance of a parametric space-time adaptive processing (STAP) method is presented here. Specifically, we consider signal detection in additive disturbance containing compound-Gaussian clutter plus additive Gaussian thermal white noise. Performance is compared to the normalized adaptive matched filter and the Kelly GLRT receiver using simulated and measured data. We focus on the issues of detection and false alarm probabilities, constant false alarm rate (CFAR), robustness with respect to clutter texture power variations, and reduced training data support.
