摘要/Abstract

摘要： 研究了基于到时测量的多传感器落点被动定位方法，并对定位误差进行了分析和数值。该方法从传感器目标信号到时得出目标落点位置测量方程，根据个传感器得到的目标落到时数据计算目标落点在的准确位置。研究结果表明，该落点定位方法是可行的，定位精度，有一定的实用价值，可直接用于地面落点目标的定位。

Abstract: The now generally used method for locating the bomb impact points on water surface is, in our opinion, still not quite satisfactory. We propose a new method which, we believe, is better. Our method is a new method of bomb impact points locating with many sensors distributed on water surface and underwater, which is based on the time difference of arrival of acoustic signal. In the full paper, we explain in much detail our new method, particularly its error analysis. In the new method, the result of time difference of arrival gained from two sensors is considered as the parameters of the target location. Based on the time difference of arrival, the location of the impact points is calculated by air measured results and underwater measured results. In our simulation research, we took a certain impact point. The locating error of our new method is smaller than that of the now generally used method.
