In order to exert the jamming efficiency of shipborne active jamming equipment against anti-ship missile terminal guid-ance radar,anti-active self-defense jamming factors and their mathematical models in the time domain,frequency domain,energy domain and identification domain are proposed based on the anti-jamming technology mechanism of anti-ship missile terminal guid-ance radar,and the calculation model of anti-active self-defense jamming capability is established too,which can support the ship-borne active jamming equipment to optimize compound jamming pattern according to the perception information(frequency,pulse width,repetition frequency,signal system,etc.)of shipborne reconnaissance equipment and the performance(jamming lead time,interference bandwidth,interference power,etc.)of active jamming equipment,so as to achieve the best matching between the jamming pattern of shipborne active jamming equipment and the terminal guidance radar of anti-ship missile.For the radar with non-coherent frequency agile waveform or coherent pulse compress waveform,the optimal compound jamming pattern under differ-ent distances between missile and target is proposed through simulation tests.
