Side-lobe cancellation system based on uniform plane array

Adaptive side lobe cancellation is an effective measure to rejecting interference without rejecting the target signal. This paper analyzes side-lobe cancellation principium based on uniform plane array, introduce the method to calculate optimal weights by matrix inversion algorithm. Finally simulation validates the cancellation performance which is valuable in appliance. It shows that the adaptive side lobe cancellation system is very effective to interference cancellation and the direction of interference estimation.
