| Abstract: | This paper is concerned with the reason why the performance degradation of the jamming suppression, when there simultaneously exist the active and passive jammings. The rigorous mathematical model is established, and the reason is also exploited from the theoretical viewpoint, which is verified by the simulated data. The results highlight that the reason of degradation of the jamming suppression in the presence of both active and passive jammings is the degradation of the sidelobe cancelling, which, in turn, is introduced by the operation of the amplitude constraint. |
