Anti-vessel end-guidance radar ECCM against deception jamming of range gate pull off

Electronic counter-countermeasures (ECCM) against range gate pull off (RGPO) are the key ability needed by anti-vessel end-guidance radars. An integrated means of jamming recognition is presented using automatic gain control (AGC) voltage, CFAR output, echo dimension and velocity of tracking gate, based on analyzing the modes of RGPO. A novel method of ECCM against RGPO using memory tracking and narrow gate monitoring is proposed. Interference of RGPO will be out of tracking gate earlier than target echo. This method can deal with all kinds of RGPO, and can apply to both coherent radars and non-coherent radars.
