摘要/Abstract

摘要： 浮标基定位系统利用水声侦察信号对待测目标进行定位时，时延测量精度是系统定位精度的关键因素。在非水声对抗条件下，传统的信号检测手段与分群开窗相结合的方法可以准确测得直达声信号时延并对待测目标精确定位，但在水声对抗情况下，由于对抗器材模拟回波的存在，传统方法的定位精度下降，甚至不能正确定位。针对这种情况，本文提出了一种基于时延匹配及信号多普勒的侦察信号辨识方法。理论分析与仿真结果证明，该方法有效可行。

Abstract: The precision of time-delay estimation is the key factor for the performance of the acoustic positioning system based on the buoy platform, when locating the target with its seeking signal. In the nonantagonistic condition, the method of separating group and opening window can measure time-delay of the direct pulse accurately and then get the position of target. But in the environment of antagonistic warfare, the traditional method will only obtain low-grade precision or even become inefficacious due to the existence of the simulated signals sent by the enemy equipment. To solve this problem, a novel method is proposed here, which is based on the matching of time-delay and the Doppler of the signal. This method can distinguish the direct pulse of target’s seeking signal from the simulated disturbance. Through theoretical analysis and computer simulation, this method is proved to be effective and feasible.
