Bayesian 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...
متن کاملSimulation 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 کاملStatistical analysis on spatial correlation of ionospheric day-to-day variability by using GPS and Incoherent Scatter Radar observations
In this paper, the spatial correlations of ionospheric day-to-day variability are investigated by statistical analysis on GPS and Incoherent Scatter Radar observations. The meridional correlations show significant (>0.8) correlations in the latitudinal blocks of about 6 degrees size on average. Relative larger correlations of TEC’s day-to-day variabilities can be found between magnetic conjugat...
متن کاملRefractivity Measurements from Ground Clutter Using the National Weather Radar Testbed Phased Array Radar
In warm seasons, convective precipitation initiation heavily depends on moisture near the surface [e.g., Dabberdt and Schlatter, 1996; Koch et al., 1997]. A necessary condition for an accurate prediction of convective rainfall is a good forecast of where and when convection will develop. Both prediction and understanding of convection is limited by the lack of high spatial and temporal resoluti...
