Abstract :
Clutter property of a forward-looking array radar on Hypersonic Vehicle is analyzed and a method for clutter suppression using multi-stage space-time adaptive processing (STAP) is proposed. This method employs the elevation degree of freedom of the planar array to extract various range ambiguous clutter. Then range-unambiguous non-stationary clutter is compensated by using Doppler Warping (DW) algorithm, and finally STAP in azimuth-Doppler domain is used to suppress the residual clutter. Simulation results are given to demonstrate the validity of the presented method.
