Abstract:

The theory of adaptive sidelobe canceller is presented in this paper.Effects of coherent coefficient on the sidelobe canceller are studied,and simulation is conducted on a computer by Matlab.The performance results between sidelobe cancellation and the correlation are verified explicitly.It is proved that the increase of relativity can degenerate the cancellation performance and weaken the effect.

Key words: sidelobe canceller;coherent coefficient;cancellation gain
