Abstract :
An approach of subarray partitioning for planar phase array radars with ADBF is presented. The architecture of subarray is optimized using genetic algorithm. With the optimized structure of the array, the sidelobe level of adaptive pattern has been well improved; meanwhile, the jammer was suppressed obviously in the direction of the jammer arrival for ADBF at the subarray level. That was demonstrated on 30x32 elements planar array.
