Study on ADBF at subarray level with sidelobe suppression performance

ADBF at subarray level has important applications in phased array radar. By generalizing the ADBF at element level we can get the conventional ADBF at subarray level, but its disadvantage is that the sidelobe level of adaptive pattern is much higher. And that MOD method can suppress sidelobe level well, but introduces biggish SINR loss. This paper combines the conventional ADBF at subarray level and MOD method, which can suppress the sidelobe level of adaptive pattern effectively and improve SINR compared with MOD. Simulation results indicate the validity of the introduced method.
