摘要: 浅海环境中运动目标可以生成稳定的干涉声场，干涉声场结构中蕴含目标的距离、速度等信息。该文提出一种利用运动目标干涉声场进行被动距离速度估计的方法——匹配干涉场处理方法。首先对浅海波导环境中的干涉现象和结构特性进行理论分析，推导了匹配干涉场方法聚焦原理。然后将运动目标的时间-频率干涉场转换成与目标距离速度相关的距离-频率干涉场，与拷贝声场进行相关处理实现目标距离速度同时估计。进一步分析了算法估距性能以及海深、声速剖面、海底海面等环境对估距性能的影响，给出了算法宽容性的仿真结论。最后通过实际运动目标的海上试验数据处理验证了所提方法的有效性。Abstract: Moving target in shallow sea environment can generate stable interference sound field, which contains information such as target distance and velocity.In this paper, a method of passive distance and velocity estimation based on moving target interference sound field is proposed. First, the interference phenomenon and structure characteristics in shallow sea waveguide are analyzed theoretically, and the focusing principle of matching interference field method is deduced. Then, the time-frequency interference field of the moving target is transformed into range-frequency interference field which is related to the target range and velocity, and the distance and velocity of the target are estimated simultaneously by correlative processing with the copy sound field. Further, the value distance performance of the algorithm and the influence of sea depth, sound velocity profile, sea surface and other sound field parameters on the value distance performance are investigated through simulation, and the simulation conclusion of the algorithm tolerance is given. At last, the validity of the algorithm is verified by the data of practical target at sea.
