摘要
通过对水下目标亮点回波信号特性的分析,建立水下目标多亮点回波模型。据此模型提出了一种基于DSP的水下目标模拟器的软硬件设计方法。该水下目标模拟器能对各种目标回波信号的强度、多普勒效应、脉冲展宽等参数进行模拟,能产生应答信号,具有实时性好、动态范围大和人机交互性强等特点,为水声设备的试验与鉴定提供了经济便捷的手段。
Based on the research of underwater target highlight signal echo character,its multi-highlights echo model is presented.By this model,the hardware and software of underwater target simulator system for acoustic is designed on the basis of the DSP.The underwater target simulator could simulate echo intensity,Doppler effect,pulse stretching and the others.It could produce response signal.The simulator has perfect Real-time performance,broad dynamic range and good man-machine conversation performance.It is an economy and convenient way for hydroacoustic equipment testing and identifying.
