Abstract An anti-jamming space-time adaptive processor rank-reduced by Multistage Nested Winner Filter(MSNWF) is presented in this paper. Such processor can overcome the need of freedom degrees in traditional array processing while maintains the computa-tional complexity requirements at a low level. Simulations proved such a processor can provide more freedom degrees under janimering senario and the ability to identify interfer-ences in a multidimensional spectrum at the AOA-frequency coordinates. Simulations also proved a low rank (D=10) is enough for the MSNWF space-time processor to approximate its full rank performance.
