摘要: 在光控相控阵列系统物理模型的基础上,分析了子阵数与旁瓣电平和主瓣偏移的关系,给出了基于旁瓣电平和主瓣偏移相结合的、直接数值搜索子阵数的算法及其实现过程,并通过计算机仿真验证了该方法的正确性.Abstract: This paper, based on the physical model of optically phased array, analyzes the relationship between the number of subarray and the sidelobe level and mainlobe deviation. It gives the realization process of the algorithm based on the combining the sidelobe level and the mainlobe deviation for solving the number of subarray by directly numerical search. And this method is verified to be correct by computer simulation.
