In bi/multi-static synthetic impulse and aperture ground-wave radar
multiple frequency-carrier signals are transmitted simultaneously by multiple antennas in the transmitting station.The returns of different carrier-frequency must be separated from one another before transmitting pattern is synthetically formed in the receiving station.Such a problem can be solved by adopting digital mixers and low-pass
but the amount of operation in this way is too large for real-time realization.Therefore
this paper presents the technique of channelized receiver based on multiphase filter bank.Compared with low-pass filter bank channelized receiver
the amount of operation of the multiphase filter bank receiver can be reduced by
N
2
(
N
is the number of channels).At last
the results of real-data process
ing with experimental system of the radar are given
which will verify the validity of this technique in such a radar system.
