Abstract

In this paper, we study issues associated with applying space-time adaptive processing (STAP) techniques in bistatic airborne applications. For ground moving target indication (MTI) radar, the clutter Doppler frequency depends on range for all array geometries other than linear sidelooking. This range dependency leads to problems in clutter suppression through STAP techniques. One aspect is that the STAP filter becomes range dependent. This paper proposes Doppler compensation using interpolation, in the angle-Doppler domain, for the modified joint domain localized (JDL) processor. Simulation results show that a significant improvement in processor performance is obtained throughout the whole frequency spectrum.
