基于测向阵列的空中飞行器瞬时无源定位

摘要

本文提出了一种空中飞行器瞬时无源定位方法，通过对测向阵列测得数据的分析，建立了相应的数学模型，然后采用遗传算法进行计算，实现了基于测向阵列的空中飞行器瞬时无源定位。计算结果表明：应用该方法可以精确地计算出空中飞行器的位置参数，从而实现对飞行器的准确无源定位，该方法在精度上能满足实际定位精度的要求，误差较小。%A instantaneous passive location method has been put for aerial vehicles in this paper. The corresponding mathematical model is built via the data analysis of the direction finding array. Using genetic algorithms to calculate instantaneous passive positioning parameters of aerial vehicles based on direction finding array. The calculation results show that: the application of the method can accurately calculate the position parameters of the aerial vehicles, and it can achieve passive accurate positioning of aircraft. The method is able to meet the accuracy requirements of the actual positioning and the accuracy error is smaller.
