摘　　要：两点源干扰是干扰雷达导引头的重要手段。但在实际应用中 ,两点源的功率不可能完全相等 ,这就为被动雷达导引头对抗两点源干扰提供了契机。本文通过数学推导得出了 :在远场 ,当导引头无模糊测角范围满足一定要求 ,只要保证足够的数据积累点数 ,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”Interference of dual sources is an effective means of counteracting Passive Radar Seeker (PRS).In 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 points the higher power source of double sources as long as the number of the seeker accumulating data and the bond of PRS angle measurement without the angular ambiguity is large enough.In this paper,It is proven by simulation experiments and math deducing.
