| 摘 要： | 本文根据实际情况建立多途信道和传播模型，由此模型提出了一种利用单水听器进行目标距离事先预知，事后修正的被动测距方法，文章分析了测距误差，在此基础上又提出了利用３个水听器组成的基阵进行运动目标被动跟踪定位的方案，根据该方案建立的定位系统进行海上试验，数据处理结果令人满意，海上试验表明，该方案是一种易于实现而又非常实用的方法。

| Abstract: | Abstract In this artical a multipath transmission model is selected acoording to the real situation. A passive localization method is raised with which the range is estimated first and corrected after the measurement is completed. We have analyzed the estimation error and established a passive localization method using a three-hydrophone array to track a moving target. A system from this idea was tested in the ocean and the results are satisfied. Acording to the results this scheme is very practical and can be realized easily. |
