Abstract
A new least-square active element pattern expansion (LS-AEPE) method is presented. With the help of this method, the array´s pattern including the element mutual coupling and platform effect can be efficiently calculated by the fast Fourier transform (FFT). These techniques are then combined with the genetic algorithm (GA) to optimise the excitation phases for a 64-element linear array mounted on a trapezoid metal plate.
