为更好地发挥舰载有源干扰装备对反舰导弹末制导雷达的干扰效能,基于反舰导弹末制导雷达抗干扰技术机理,提出了时域、频域、能域、识别域等抗有源自卫干扰因子及其数学模型,并建立了抗有源自卫干扰的能力计算模型,以支撑舰载有源干扰装备根据舰载侦察装备的感知信息(频率、脉宽、重频、信号体制等)以及有源干扰装备的性能(干扰引导时间、干扰带宽、干扰功率等),合理选取最佳复合干扰样式,从而实现了舰载有源干扰装备干扰样式与反舰导弹末制导雷达的最佳匹配。针对非相参捷变频信号体制雷达和脉压相参信号体制雷达,通过仿真试验提出了不同弹目距离下的最佳复合干扰样式。

In order to exert the jamming efficiency of shipborne active jamming equipment against anti-ship missile terminal guidance 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 guidance radar, and the calculation model of anti-active self-defense jamming capability is established too, which can support the shipborne 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 different distances between missile and target is proposed through simulation tests.
