摘　　要：以三角波调频无线电引信为对象,分析了调频引信的信号特征,针对低信噪比宽带连续波线性调频信号的检测,提出了基于延迟相乘的频带压缩检测算法。通过仿真试验验证,该算法对负信噪比宽带线性调频信号检测有较高的处理增益,且处理简单,工程可实现性好,满足对无线电引信信号高截获处理要求。The characteristics of triangular continuous wave FM radio fuse are analyzed, and band- compress arithmetic is introduced by delay multiplication. The process results are emulated in differ- ent conditions. The way proposed is verified that can distinguish the FM radio fuse from the complex electromagnetic environment.
