ABSTRACT: Since the sidelobe of the range compressed LFM signal is engendered high in SAR system,
this paper proposes a novel sidelobe suppression method within SAR imaging procedure based on transforming
SAR work mechanism. Chaotic sequence is introduced to the transmitter to generate N chaotic modulation
signals orthogonal to each other. In the receiver, echo signal is respective imaging after orthogonal ...
