摘　　要：针对传统遗传算法的无源测向定位容易出现"早熟"现象,提出基于实数编码遗传算法,改进了遗传算子,并且通过仿真实验,采用测向交叉定位对辐射源进行定位,实验表明,该算法既保留了种群的优秀基因,又保持了种群的多样性,有效提高了定位的精度。Aiming at the precocious problem of traditional genetic algorithm used in passive location,an improved genetic algorithm based on real encoding is proposed. The proposed method is used in bearing-crossing locating to radar emitter. Experiments show that the proposed method maintains the excellent genes and diversity of the population,and effectively improve the accuracy of positioning.
