摘要

摘要: 为提高攻潜鱼雷末弹道测量系统的被动定位精度, 文中提出了一种基于短时互谱法的攻潜鱼雷末弹道被动定位方法, 介绍了运用该方法建立的测量系统, 给出了目标的被动定位算法, 在测量区域内对测角精度、噪声影响以及典型轨迹进行仿真分析。仿真结果表明, 在信噪比为10 dB的条件下, 采用文中的定位方法, 当目标位于距测量子阵80 m, 角度为±40°区域内的弧线上, 测向精度提高0.15°, 典型航迹绝对误差普遍减小0.4 m。文中所做研究可为考核鱼雷效能评估提供参考。

Abstract: A passive location method based on short-time cross spectrum method is proposed to improve the passive location accuracy of a torpedo terminal trajectory measurement system. The measurement system established according to this method is introduced, the passive location algorithm of a target is given. The angle measurement accuracy, the noise influence and the typical trajectory are simulated and analyzed in the measuring area. Simulation results show that for the signal-to-noise ratio(SNR) of 10 dB, when the target is on the arc of an ±40° region and the distance between the arc and the measuring subarray is 80 m, the direction finding accuracy of the proposed location method is improved by 0.15°, and the absolute error of typical trajectory is generally reduced by 0.4 m. This research may provide a reference for evaluating torpedo effectiveness.
