摘要: 從單站序貫測(cè)向無(wú)源定位的誤差分析出發(fā)，提出了基于遺傳算法的最大似然只測(cè)向(Bearing-Only)定位方法，并以最小二乘法進(jìn)行粗估計(jì)，對(duì)遺傳算法采用了一維編碼改進(jìn)。實(shí)驗(yàn)表明，該方法既提高了算法的精度，又解決了二維定位中遺傳算法搜索空間過(guò)大的問(wèn)題，提高了算法的實(shí)用性。

Abstract: 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. -
