Abstract

Based on the characteristics of cosite coupling interference between transmitting and receiving antennas in a same battleship, a novel approach using the normalized least mean square (NLMS) algorithm to suppress the interference is proposed. Firstly, this paper analyses the principle of adaptive interference cancellation (AIC), then a simulation example is offered to show the implementing effect of the method. The results demonstrate that the AIC method can be used effectively to suppress the coupling interference between the transmitting and receiving antennas in battleships.
