本文简述了相干两点源干扰反雷达导弹被动雷达导引头的基本原理;分析了相干两点源在空间相干场的栅瓣特性,非畸变区与畸变区的相位特性,根据这些特性,分析被动雷达导引头在远场与近场跟踪相干两点源的性能,分析研究抗反雷达导弹的可能性,提出适当选择两点源之间的距离L和两点源的电压幅值比β,有可能将反雷达导弹诱偏于两点源之外。本文为进一步定量分析两点相干源抗反雷达导弹的效果,提供了一定的理论基础。
In this paper, the basic principle of the passive radar seeker with two coherent two-point source interfering anti-radar missiles is briefly introduced. The phase characteristics of the grating lobe, the non-distorted region and the distorted region of the coherent two-point source in the spatial coherent field are analyzed. According to these characteristics, The passive radar seeker is used to track the performance of two sources in the far field and the near field, and the possibility of anti-radar radar is analyzed. The appropriate choice of the distance L between two sources and the voltage amplitude ratio β, it is possible to induce anti-radar missiles at two sources. This article provides some theoretical basis for further quantitative analysis of the effect of two-point coherent source anti-anti-radar missile.
