| 摘 要： | 现代雷达系统一般采用子阵的形式减少通道数,均匀划分的子阵有利于减小微波网络的实现难度,但形成多波束时会出现栅瓣。为此提出一种基于遗传算法搜索权值,包括阵元权和通道权形成多波束,以降低栅瓣,改善多波束性能。仿真实验表明,该方法是有效可行的。

| Abstract: | Modern radar systems usually adopt the form of subarray in order to reduce the number of channels.The performance of multi-beam is degraded due to the grating lobe which appears at the uniform subarray set which contribute to actualize the microwave net.A method based on genetic algorithms to search the weights of multi-beam at elements level and channel level is proposed for the purpose of reducing the grating lobe.The results turn out the validity of the method. |
