Amplitude and phase adaptive nulling with a genetic algorithm

This paper introduces amplitude and phase nulling with a genetic algorithm with the intent of finding the optimum number of LSB of control needed to p lace multiple nulls while not significantly distorting the far field patter n. Many interference scenarios were modeled and individual runs were averag ed to conclude that five LSB of amplitude and three LSB of phase control ou t of a total of eight bits are best for the linear array modeled. Represent ative samples of some of the interference scenarios modeled are shown.
