| 摘 要： | 被动声探测目标的定距定位技术，是反坦克、反直升机智能雷弹的关键技术。该文讨论了利用时延法进行被动定位的基本原理，以及采用后置处理的必要性，提出一种简单并有较好效果的后置处理方法，即采用预处理方法，剔除被动测距中的野值，用卡尔曼滤波作为后置处理的基本手段，平滑目标的运动轨迹，降低了误差。这种方法经计算机模拟和以坦克为目标的实验，显示出良好的工作性能，给出了满意的目标距离、速度和方向估计。

| Abstract: | The range and direction measurement of a target is a key technic of antitankand antihelicopter smart mines. The passive location principle utilizing time delay method and the necessity of post processing were discussed. We applied Kalman filtering method as a basic means in post processing of passive sound finding fuse systems,eliminated wild values of passive detecting and ranging,made the objective motion path curve smooth, aswell as reduced the error of processing.This metho.d presented perfect performance in computer simulation and passive sound finding experiment with tanks.A set of satisfied distance,velocity and direction estimating result has been obtained. |
