Abstract :
A novel approach for interference rejection is introduced. The optimum weight vector is solved by minimizing the signal-free data obtained from subarray processing under the constraint of a unit gain maintained in the look direction. The proposed method is valid for any correlated sources, and can combat signal cancellation thoroughly. Results of simulations are also given to illustrate the performance of the proposed approach
