Abstract This paper analyses the airborne radar ground clutter suppression abilitv of DPCA by decomposing the clutter zone into small celis, and points out that DPCA is a shnple tinic-space processor. This paper also analyses the reason that lowers the DPCA performancc and proposes a DPCA method based on clutter frequency shift. Theoretical analysis and simulation show that this method s performance is good and it is easy to implement.
