低空目标被动声定位误差仿真

Low-altitude Target Passive Localization Error Simulation

针对低空目标声场特性,在到达时延(Time Delay of Arrival,TDOA)定位算法基础上,建立一种针对低空目标定位误差的数学模型GDOP(Geometric Dilution Precision)。对常用的布站方式进行定位误差仿真分析,从仿真结果中可以得出最优布站方式,此数学模型可作为衡量低空目标定位最优布站方式之一。

Aiming at low-altitude targets feature,a mathematical model GDOP（Geometric Dilution Precision）is established based on the TDOA（Time Delay of Arrival）.The error simulation is used for analyzing commonly used station placement in the model and then finds the best pattern of station placement.So the mathematical model can be used as one of the best way to measure low-altitude target location station placement.
