| Abstract: |
| This paper is concerned with the reason why the perform
ance degradation of the jamming suppression, when there simultaneously exist the
active and passive jammings. The rigorous mathematical model is established, an
d 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 i
s the degradation of the sidelobe cancelling, which, in turn, is introduced by th
e operation of the amplitude constraint. |
