针对机载两源反向交叉眼干扰在实际应用中遇到的参数容限严苛和干信比需求高的问题,提出了一种创新的解决方案,即利用电子战无人机(EWUAV)搭载反向交叉眼干扰机对敌方制导雷达进行抵近干扰。首先,建立了EWUAV 反向交叉眼干扰模型,通过深入分析该模型,揭示出机载两源反向交叉眼干扰模型实则是其一个特例;其次,在确定干扰有效性方面,设定了一个明确的指标:当视在假目标的爆炸范围不触及被保护平台的物理边界时,即认为干扰达到预期效果。此外,文中还详细推导了雷达指示角,创新性地将其参数分为几何与电参数两类进行深入分析;最后,通过一系列仿真实验,充分证明了所提方法不仅有效,而且在参数容限和干信比需求方面表现更为宽松和优越。

Aiming at the problems of strict parameter tolerance and high interference signal ratio encountered in the practical application of airborne two source retrodirective cross-eye jamming, an innovative solution is proposed in this paper, that is, using electronic warfare unmanned aerial vehicle (EWUAV) carrying retrodirective cross-eye jamming to approach enemy guidance radar. Firstly, EWUAV retrodirective cross-eye jamming model is established in this paper. Through in-depth analysis of the model, airborne two source retrodirective cross-eye jamming model is actually a special case of it. Secondly, in determining the effectiveness of jamming, a clear indicator is set: when the explosion range of the apparent false target does not touch the physical boundary of the protected platform, the jamming is considered to have achieved the expected effect. In addition, the radar indication angle is derived in detail, and its parameters are innovatively divided into geometric and electrical parameters. Finally, through a series of simulation experiments, it is fully proved that the proposed method is not only effective, but also more relaxed and superior in parameter tolerance and interference signal ratio requirements.
