摘　　要：针对大型的二维平面阵列天线,将随机布阵的概念应用于子阵布阵中,提出基于子阵的随机错位布阵方式,并采用二进制粒子群算法对随机错位子阵的错位方式进行了优化。仿真结果表明:采用随机错位子阵布阵方式,通过粒子群算法优化后,平面阵列天线可以在扫描范围内得到较低的旁瓣,避免了栅瓣的出现。For the large plane antenna arrays with subarrays, the randomly staggered structure is applied to decrease the grating lobes. Binary particle swarm optimization （BPSO） algorithm was used to find the optimal structure of the randomly staggered subarrays. Simulated results show that the plane antenna arrays with subarrays of this new structure can get low side lobe in the scanning range.
