Research on phased array antenna multi-step mixed feed

This paper proposes a novel phased array multi-step mixed feed method using Active Mutating Anneal-Genetic Algorithm(AMAGA) based on sorting. It describes phase array antenna ultra low side lobe technique theory and simulation examples in the case of finite TR module number or variety. In comparison with the density weighed method and multi-step amplitude quantization method, the multi-step mixed feed method is more flexible. Moreover, simulated examples show more lower side lobe than the latter two methods.
