一种基于改进遗传算法的只测向无源定位技术

A Bearing-Only Passive Location Method Based on Improved Genetic Algorithm

从单站序贯测向无源定位的误差分析出发,提出了基于遗传算法的最大似然只测向(Bearing-Only)定位方法,并以最小二乘法进行粗估计,对遗传算法采用了一维编码改进。实验表明,该方法既提高了算法的精度,又解决了二维定位中遗传算法搜索空间过大的问题,提高了算法的实用性。

Analyzing errors of single observer-sequential BO （Bearing Only） passive location technology, a Maximum likelihood method is introduced based on 1-D coding improved genetic algorithm, in which basic least square algorithm is applied for pre-estimation. Simulations show that the method has both high precision and high practicality, for it overcomes the large search space of genetic algorithms in 2-D location.
