Adaptive wideband sidelobe cancellation based on uniform line array

Sidelobe cancellation is an important method of anti-jamming technologies. This paper proposes an adaptive wideband sidelobe cancellation system base don uniform line array. In this system, calculate the weight of auxiliary channel by the subbands with interference and then weighted the auxiliary channel signal to obtain the jamming signals to achieve interference cancellation. The simulations show that the system can restrain two jamming signals effectively.
