摘　　要：对机载有源相控阵雷达系统,进行子阵级ADBF应用研究,运用遗传算法来对子阵形式优化,并结合对角加载技术,实现小采样本条件下波束快速收敛。仿真结果表明,优化后的子阵,自适应副瓣电平得到很大的改善,同时,在干扰方向形成明显的零深。On airborne planar phased array, an approach of subarray partitioning with adaptive digital beam forming （ADBF） is studied. The architecture of subarray is optimized using genetic algorithm. With the diagonal loading technique, beam shape can be rapidly converged in short sample period. Simulation results are presented, the sidelobe level of adaptive pattem has been shown well improved;and the jammer was suppressed in the arrival direction of the jammer for ADBF at the subarray level.
