Simulation of the Radar Ground Clutter Based on DEM
The simulation of ground clutter is the key and knot problem in radar simulation system. The simulation of ground clutter based on DEM is studied. It is introduced how to use fractal arithmetic to produce random digital elevation. After obtaining the orographic’s height, draw the 3D terrain with the OpenGL technology, in order to realize the demonstration of 3D terrain. Based on DEM, terrain is...
متن کاملClutter mitigation techniques for space-based radar
The mission of a ground moving target indication (GMTI) radar, as its name implies, is to detect and classify ground-based vehicles, even ones with very low velocities. This type of radar can provide a wide area of coverage and frequent updates of a specific area of interest if the radar is placed on a satellite with a low earth orbit. However, because of the large footprint of the radar on the...
متن کاملRadar cross-section (RCS) analysis of high frequency surface wave radar targets
Realistic high frequency surface wave radar (HFSWR) targets are investigated numerically in terms of electromagnetic wave – target interactions. Radar cross sections (RCS) of these targets are simulated via both the finite-difference time-domain (FDTD) method and the Method of Moments (MoM). The virtual RCS prediction tool that was introduced in previous work is used for these investigations. T...
متن کاملBayesian Optimum Radar Detector Performances Against Ground Clutter Data
In this paper detection performances of the Bayesian Optimum Radar Detector (BORD) against nonGaussian ground clutter data are showed in the case of an unknown complex amplitude target. Recalling first how BORD was derived from the non-Gaussian SIRP model (Spherically Invariant Random Process) clutter we derive theoretical performances of the asymptotical expression of BORD which is CFAR with r...
متن کاملInfluence of Ground Clutter Contamination on Polarimetric Radar Parameters
The influence of ground clutter contamination on the estimation of polarimetric radar parameters, horizontal reflectivity (Zh), differential reflectivity (Zdr), correlation coefficient (rhy), and differential propagation phase (fdp) was examined. This study aims to derive the critical level of ground clutter contamination for Zh, Zdr, rhy , and fdp at which ground clutter influence exceeds pred...
