Abstract : A sidelobe suppression system including an antenna with a variable phase center, a transmitter for transmitting an expanded phase-coded pulse, a receiver for receiving target echoes, a pulse expander/compressor for phase coding the expanded transmitted pulse with a phase code, P, and for compressing target echoes with unscrambled phase code P and a control unit for shifting the phase center of the antenna to scramble the phase codes of the expanded pulses transmitted into the antenna sidelobes.
