摘要/Abstract

摘要： 针对相控阵导引头中存在的误差和干扰对阵列波束的影响,提出了权值近似和遗传算法结合的递进型算法实现对波束的最大优化。该算法综合考虑了阵列的互耦效应对波束的干扰以及量化误差,在权值近似的基础上将阵列波束的旁瓣电平、零深和波束宽度作为优化指标,引入遗传算法不断逼近实现波束的优化。该递进算法在权值近似的基础上优化,进一步提升了波束的性能,同时具有很强的灵活性。

Abstract: Aiming at the influence of errors and interference in the phased array seeker on the array beam,proposes a progressive algorithm combining weight approximation and genetic algorithm to achieve the maximum optimization of the beam.The algorithm comprehensively considers the interference of the mutual coupling effect of the array on the beam and the quantization error.Based on the approximate weights,the sidelobe level,zero depth and beam width of the array beam are used as optimization indicators,and genetic algorithms are introduced to continuously approach the realization of the beam Optimization.The progressive algorithm is optimized on the basis of approximate weights,which further improves the performance of the beam and has strong flexibility.

Key words: phased array seeker, approximate weight, genetic algorithm, progressive algorithm, mutual coupling effect, quantization error
