摘　　要：针对单枚浮标对目标检测能力有限的问题,为了提高对目标的检测性能,根据多枚空投浮标的位置和信息特点,对多枚浮标的检测级融合进行了研究;在对分布式检测融合理论进行研究的基础上,研究了基于分布式检测的浮标信号检测级融合体系结构、融合规则、融合算法等。通过仿真验证,给出了各浮标及融合系统的检测性能曲线,及相关系数、接收机信噪比等参数与检测性能的关系。仿真分析结果表明:经过融合后的浮标信息检测性能优于单枚浮标的检测性能。The detection capability of single buoy is limited. To improve detection performance, we studied the detection-level fusion of several buoys based on the position and information characteristics of several airdropped buoys. On the basis of the analysis to distributed detection fusion theory, we studied the structure, rule and algorithm of the buoy signal detection-level fusion based on distributed detection. Detection performance curves of each buoy and buoy fusion system, and the relationship of related coefficient and receiver＇s SNR with detection performance were provided through simulation validation. The results of simulation showed that the detection ability of the fusion system is better than that of single buoy.
