Abstract:

In this paper, an improved direct data domain method is studied for airborne radar with uniform circular array antennas in STAP. Based on a single snapshot, this algorithm can effectively restrain jamming and clutter while keeping the signal of interest. By implementing multiple space-time constraints, the system gain is maintained
when the signal of interest deviates slightly. Experimental results show effectiveness of the method.

Key words: uniform circular array, multiple constraints, real weight, direct data domain method, space-time adaptive processing
