摘　　要：近年来,因航空事业发展快速,飞行密度增大,二次雷达应答交织概率大幅提升,影响航空运输安全。但针对二次雷达应答交织国内外系统性研究资料较少,本文从二次雷达应答交织的现象出发,结合理论分析深入寻求交织的本质原因,讨论应答信号交织的解码准则和基本提取方法,推论出两批交织目标理论上的正确解交织概率,提出提高解交织概率的方法,并在实验室环境测试得到验证,本文提出的方法可在二次雷达研制中广泛推广应用。In recent years,due to the rapid development of aviation industry and the increase of flight density,the interleaving probability of SSR response has increased significantly,which affects the safety of air transportation.However,there are few systematic research data on SSR response interleaving at home and abroad.Starting from the phenomenon of SSR response interleaving,combined with theoretical analysis,this paper deeply seeks the essential reason of interleaving,discusses the decoding criteria and basic extraction methods of response signal interleaving,infers the correct de interleaving probability of two batches of interleaving targets in theory,and puts forward the method to improve the de interleaving probability,the method proposed in this paper can be widely used in the development of SSR.
