国内外对于波束综合技术虽已进行了大量的研究开发工作，但主要集中在接收系统，而对于发射波束研究相对较少。基于工程需要，提出了一种改进的二进制遗传算法实现相位量化的唯相位低副瓣波束综合技术，并给出了实验数据和性能曲线。理论分析和实验结果表明该算法在大多数情况下能有效降低副瓣，且主瓣宽度不变，因此该算法具有较大的实际意义。
國內外對于波束綜閤技術雖已進行瞭大量的研究開髮工作，但主要集中在接收繫統，而對于髮射波束研究相對較少。基于工程需要，提齣瞭一種改進的二進製遺傳算法實現相位量化的唯相位低副瓣波束綜閤技術，併給齣瞭實驗數據和性能麯線。理論分析和實驗結果錶明該算法在大多數情況下能有效降低副瓣，且主瓣寬度不變，因此該算法具有較大的實際意義。

Many researches and developments for beam synthesis technique have been carried through at home and abroad ,but the focal point is receiving system ,the research into the transmit-ting beam is relatively less .Based on the engineering requirement ,this paper puts forward a low side-lobe beam synthesis technique based on phase-only by using improved binary system genetic algorithm to realize phase quantization ,and gives the experiment data and performance curve .The theoretical analysis and experiment result indicate that the algorithm can effectively decrease side-lobe generally ,and the main lobe width doesn't change ,so the algorithm has biggish practical mean-ing .
