针对毫米波引信波导缝隙阵天线在固定的小体积内难实现低副瓣的问题，提出了一种基于改进的遗传算法降低毫米波导缝隙阵天线副瓣电平的设计方法。该方法利用 Matlab 编程计算得出缝隙参数及其泰勒线阵阵元激励幅度，通过改进的遗传算法优化泰勒线阵阵元激励幅度，有效地降低了毫米波波导缝隙阵天线副瓣电平。仿真结果表明，采用这种基于改进遗传算法的波导缝隙阵天线设计方法，使得天线的副瓣电平降低了3.83 dB。

An improved genetic algorithm was put forward to solve the problems of the lower side lobe of milli-meter wave fuzes waveguide slot array antenna for the space limitation.The method used improved genetic algo-rithm to reduce side lobe level.In this paper,the Matlab program were used to compute Taylor distribution of slot array antenna.And because of the improved genetic algorithm applying to the optimization design of the Taloy array distribution,the side lobe was effectively reduced.Simulation results showed that this design meth-od of millimeter wave waveguide slot array antenna ccould reduce the side lobe by 3.83 dB lower.
