摘　　要：针对多枚被动声纳浮标进行联合探测的问题,利用声纳浮标信号多径传播模型和舰艇频谱特征提出了一种新的分布式检测方法。根据检测融合理论和似然比检验理论,在给定单枚浮标探测性能条件下,给出融合检测概率的计算方法。仿真分析验证了所提方法的有效性,并为多枚被动声纳浮标联合探测以及效能评估提供了理论和工程基础。For associated detection problem of multi passive sonobuoys, a new distributed detection method is proposed based on the model of multipath propagation and the spectrum characteristics of the ship.the detection fusion theory and likelihood ratio test theory are used, optimal detection fusion algorithm is studied, computa- tion method of fusion detection probability for single sonobuoy is presented. The effectivity of the method is validated via simulation analysis, the theory and approach foundation are provided for analysissitus structure de- sign and capability analysis of multi passive sonobuoys associated detection.
