摘要
本文根据实际情况建立多途信道传播模型。由此模型提出了一种利用单水听器进行目标距离事先预估,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了海上试验,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。本文根据实际情况建立多途信道传播模型。由此模型提出了一种利用单水听器进行目标距离事先预估,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了海上试验,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 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.
