面对新一代相控阵体制雷达,采用传统的基于空域、时域、频域大范围“遮盖冶自卫干扰,效率低,干扰效果受限,还带来电磁兼容、电磁暴露等问题。精准干扰是提升对相控阵体制雷达综合对抗效能的有效解决途径。文中对相控阵体制雷达精准自卫干扰技术开展了研究,分析了相控阵体制雷达精准自卫干扰系统设计的主要考虑因素,构建了相控阵体制雷达精准自卫干扰系统的系统架构,在此系统架构上建立了精准自卫干扰数学模型,并通过数字仿真验证了模型的有效性。

For the new generation phased array radar, traditional self-screening-jamming (SSJ) is inefficient and limited, which is based on wide range of “covering”in spatial-domain, time-domain and frequency-domain. Simultaneously, it also brings other problems such as electromagnetic compatibility and electromagnetic exposure. The precision jamming is an effective means to improve the comprehensive effectiveness for counteracting phased array radar. In this paper, the precision SSJ technology for counteracting phased array radar is studied. To design the precision SSJ system that is used to counteract phased array radar, the main factors in system design are analyzed, and the architecture of system is constructed. The mathematical model of precision SSJ is established on the basis of the system architecture and the validity of the model is verified by simulation.
