Method of ground clutter simulation in range gate signal level for airborne bistatic radar

  • Ground clutter simulation of bistatic radar is complex due to the variety of geometry configuration. The method of clutter scatterer division in monostatic radar can be applied to bistatic radar, while it is inconvenient for clutter analysis in specific range gates. One clutter simulation approach in range gate signal lever for airborne bistatic was proposed based on the comparison between ground equidistance traces of bistatic and monostatic radar. The equidistance ellipse rings were divided with two-way distance resolution in range direction, the expression of ground ellipse was deduced, and the analytic resolutions of scatterers were presented. In azimuth direction the clutter cell grids were dispersed by introducing intermediate variable guaranteeing the Doppler resolution, and the computing processes of unknown parameters used in clutter simulation were presented. The approach can complete not only the simulation of clutter spectrum for overall area observed, but also the computation of the clutter echoes in one or some special range gates. Simulation results prove the validity of the method.
