摘　　要：为快捷检测声纳系统工作状态,在分析水下目标回波特性的基础上,以十字阵为例推导了水下目标运动轨迹公式、回波仿真模型及噪声仿真方法。在VC++环境下开发声纳目标模拟系统的仿真软件。通过与声纳系统的联调,给出仿真数据与实测数据的对比结果,数据误差在声纳系统允许范围之内。试验结果验证了设计方法的有效性。Based on the software emulation technique, a new design of sonar target simulation system is proposed in this paper. A cross array is taken as an example to analyze the characters of underwater echo signal. The targets trajectory formula, noise and echo emulation model, are derived. The emulation software is developed in VC ＋ ＋ environment. Through the experiments between simulation system and sonar system, the comparison of simulated data and measured data is given. The data error is allowable in the sonar system and the validity of this design is proved.
