Statistical Analysis and Simulation Method of Forward Scattering Clutter in Bistatic Radar

The research of statistical properties and simulation methods of radar clutter has vital importance to the design, simulation and development of radar systems. Based on the analysis of some experimental data of forward scatter radar (FSR) clutter, it was found that at low wind speed and in narrow dynamic range, the amplitude of FSR clutter was subject to K distribution; while at high wind speed or in wide dynamic range, it was subject to lognormal distribution; the power spectrum was subject to the all-pole model. With the above statistical analysis, the forward scattering coherent clutters were simulated using a method combining zero-memory nonlinear transformation with spherically invariant random process. The statistical properties of simulated clutter were identical to those of measured clutter, which verified the validity of this method.
