NEW METHOD FOR REDUCED RANK STAP—NON CLUTTER CHANNEL METHOD

摘要

For reduced rank space time adaptive processing(STAP) in airborne radar, this paper presents a new method — non clutter channel(NCC) method which is easy to implement in real radar systems. The NCC method uses those “channels” located in the non clutter domain to construct the reduce rank transformation matrix. This method avoids eigen decomposition and the computational cost is very low. The performance is compared with that of several other methods; the simulation demonstrates that the NCC method can well approach the optimum performance and even outperform some more complex methods in low rank.
