Space-time adaptive processing (STAP) is used widely in airborne and space-based radar as a key techniques of MTI because of its superior Clutter Suppression performance. This paper firstly introduces the geometry of chutter of airborne radar, and elaborates the basic principle of STAP of airborne phased array radar. Then several jamming methods are proposed on the base of its weakness and limits and explaining its reasons at the same time, which builds a valid foundation for the realization of jamming for STAP technique. The proposed jamming methods have some theory value.
