摘要：
Null steering in rectangular planar arrays has been achieved when only the amplitudes of the array elements are perturbed. Genetic algorithms were employed to solve the problem of null steering in uniform and Chebyshev planar arrays. Mathematical expressions for the planar array factor were derived from the linear array factor expression. The results show that nulls can be accurately steered to the required real space directions with the minimal disturbance to the other array parameters and at the same time achieve any prescribed null depth.
