Phased array antenna uses phase shifters to change the beam direction, thereby introducing the periodic quantization lobe,and raising the peak sidelobe level. The appropriate two probable Value (A2PV) can effectively suppress the parasitic lobe. But the A2PV method result is an average optimum of a statistical sense. The peak sidelobe is random and has large variance. This paper introduces the adaptive genetic algorithm(AGA) to optimize the A2PV result. It can effectively suppress the parasitic sidelobes, reduce the peak sidelobe, and determine the scanning wave control code. The simulation results show that AGA can achieve a stable and better feed distribution.
