PSO Algorithm for Amending the Minus Beam Pointing Error After Phase Defocusing

摘要：

The minus beam steering of the phased arrays deviates from the given direction because of the quantization phase in the digital phased shifter.This paper studied the theory of wide-beam and “minus beam and investigated the model of the particle swarm optimization method on the arrays’ beam steering,and modified the range of the position and speed factor by the principle of random phase quantization.The simulating results show the effectiveness and correctness of the method.
