Abstract

Abstract:

The clutter spectrum depends highly on the range for forward-looking radar, which results in the heterogeneous ground clutter in space-time adaptive processing (STAP). According to the clutter model, a novel method is proposed. The method firstly uses the Bessel function to separate the azimuth from the elevation, and the spatial-time steering vector could be represented as the azimuth and elevation vector kronecker product to each range gate. Secondly, a transform matrix could be obtained by projecting the training unit of the elevation vector to the tested, which is applied to process the data at a given Doppler gate, and eliminate the heterogeneous ground clutter and generate a sufficient data to construct the new covariance matrix. Finally, the conventional STAP could be applied to the clutter suppression. Simulation results verify the effectiveness of the proposed method.
