Interrupted-sampling jamming (ISJ) is a big threat to large time-band
width radar. In order to enhance anti-jamming capability of radar, it is
a key problem to filter the jamming without harm to target information.
To solve the problem, this letter proposes a new method to filter the
jamming by designing filers dividedly after estimating the ISJ
parameters. The filters change the state of jamming and make it fused
with the echo. Experiments show that this method can divide the jamming
and echo. The reduction of ISJ is about 6dB
