Abstract

Abstract:

The clutter spectrum depends highly on the range and frame of bistatic airborne radars, which results in heterogeneous ground clutter and inaccurate estimation of the clutter covariance matrix in space-time adaptive processing (STAP). A new method for the compensation of the clutter spectrum is proposed. The method first gives a transform matrix by fitting the spatial steering vector of the range gate under test to that of the secondary range gate. The transform matrix is then applied to spatial data at a given Doppler gate to compensate the clutter spectrum, thus achieving an identical clutter spectrum. The conventional STAP could exploit the compensated data for the clutter suppression. Simulation results show a good improvement in processor performance.

Key words: spatial steering vector fitting, bistatic airborne radar, clutter spectrum compensation
