Cross Beam STAP for Nonstationary Clutter Suppression in Airborne Radar

الملخص EN

A novel space-time adaptive processing (STAP) method for nonstationary clutter suppression is proposed.

The developed method forms a multibeam along the cross line to participate in adaptive processing, which sufficiently utilizes the spatial information both in azimuth and elevation and guarantees the least system degrees of freedom (DOFs).

The characteristics of this structure help to suppress the short-range clutter which is the primary component of nonstationary clutter.

Therefore, this method provides favorable clutter suppression performance when clutter range dependence exists.

Approach analysis and simulation results are given to demonstrate the effectiveness of the method.
