A new algorithm for the optimal pattern synthesis of arbitrary arrays with prescribed broad nulls is presented, this method is similarly to the quadratic beampattern constrains method. The approach is to assume that the given array elements are used as elements of an adaptive array, with the adaptive beamforming theory, angles of interferences can be obtained, the null width and gain is controlled by introducing a large number of interfering signals at several angles throughout the prescribed broad nulls. Using the recursive least squares method, the width and relative gain of the broad nulls can been gotten
