摘　　要：两点源干扰是干扰被动雷达导引头 (PRS)的有效手段。但在实际应用中 ,两点源的功率不可能完全相等 ,这就为PRS对抗两点源的干扰提供了契机。通过理论分析和仿真实验证明 ,当两点源偏离导引头的电轴方向不大的情况下 ,只要保证足够的积累点数 ,导引头进行数据积累取均值 ,其结果并不指向两源的“重心”或“质心”而是指向两源中功率较大者 。Interference of dual sources is an effective means of counteracting passive radar seeker (PRS) In the practice,the power of dual sources is hard to be the same, so it is possible for PRS to counteract interference of dual sources In far field, PRS will not follow the power centroid and point the higher power source of double sources as long as the number of the seeker accumulating data is large enough It is proven by theoretical analysis and simulation experiments. And the formulation of the number of the seeker accumulating data is given
