高精度航空吊放声呐目标模拟技术

High Precision Technique for Searching Simulated Submarine Target with Aviation Sonar

提出一种用于航空声呐水下目标的模拟技术和设计方法，经海上试验取得了满意的效果。该方法采用以增益可控部件为核心的步进式增益控制技术，对信号进行大范围动态压缩；采用数字波形存贮技术对接收到的声呐信号进行实时处理和存贮；通过参数设置，完成水下真实目标（潜艇）的回波目标模拟。

We applied two gaincontrolled components, which contained many electronic circuits, to performing largescale dynamic condensing of echo signals and we utilized digital waveform store technique for realtime processing and storing of echoes of aviation sonar signals. In our experiments, we simulated submarine with a moving target whose motion parameters were set to be those of a real submarine. Thus we accomplished the simulation of echoes of aviation sonar signals reflected from a submarine. We applied our method to research of aviation antisubmarine equipment and achieved satisfactory results.
