研究了主动全向浮标探测信号模拟技术并进行了工程实现，为外场检测校准机上浮标搜潜系统提供了一种手段。以FPGA为控制核心，设计了信号生成算法模块及目标强度设置算法模块，实现了对主动全向声纳浮标的发射信号的模拟；通过叠加目标强度、多普勒频移等潜艇目标信息实现了对主动全向声纳浮标探测信号的模拟；搭建了实验验证系统对生成的单频(CW)信号和线性调频(LFM)信号的特性进行了测试，实验结果表明模拟的主动全向声纳浮标探测信号性能较好，本文研究内容有明确的军事应用价值。
Active omnidirectional buoys detecting signal simulation technology was studied and the system was implemented, a means for the field testing calibration machine buoy search system was provided. With FPGA as the core, the signal generation algorithm module and target strength set algorithm module were designed and active omnidirectional sonobuoy emission signal simulation was designed. By superposition of target strength, Doppler frequency shift of submarine target information, the simulation of active Omnidirectional sonobuoy detecting signal was realized. An experiment system had been set up, the generated CW signal and LFM signal were tested and the experimental results showed that simulation of active Omnidirectional sonobuoy detecting signal performance was good, the research contents of this paper have very definite military application value.
