Abstract :
Based on the characteristics of cosite coupling interference between transmitting and receiving antennas in a same battleship, this paper analyses the principle of interference suppression using adaptive interference cancellation (AIC) method, and describes an implementing scheme. At last, an experiment programme and some results are provided to demonstrate the effectiveness of the AIC system. Experiment results prove that an interference cancellation rate (ICR) about 40 dB can be achieved using this method.
