摘要: Retransmitting deception jamming (RDJ) degrades and misleads the Synthetic Aperture Radar (SAR) image interpretation by forming false targets. The beyond-Pulse Repetition Time (PRT) RDJ enlarges effective area without constraining jammer location to reduce spaceborne SAR working effectiveness. In order detect beyond-PRT enhance efficiency in electronic countermeasure environment, transmitting pulse encoding method for use is proposed based on geometry signal models of RDJ. Optimum binary codes with maximum number detection windows are determined procedure. detected found be proportional code length efficiencies even odd analyzed. simulation results validate effectiveness SAR.
