Upper limit of cancellation ratio of sidelobe canceller

CHANG Jin-dan YI Zheng-hong GAN Rong-bing(National Information Control Laboratory,Chengdu Sichuan 610036,China)  
The paper proposes constructing an ideal sidelobe canceller and an ideal signal environment,and on this basis,analyzes the upper limit of cancellation ratio of sidelobe canceller.It induces the exact expression and approximate expression of the upper limit.It shows that the upper limit of cancellation ratio of sidelobe canceller depends on the jammer-to-noise ratio in the auxiliary channel and the number of auxiliary channels.In the end,corresponding simulation results are proved to validate the theoretical analysis.
