Abstract EN
Multiple carrier frequency detecting signals are transmitted simultaneously by multiple transmitters in multistatic sonar.
The echoes mixed with different carrier frequency in the receiver.
The different carrier frequency echoes must be separated from one another before features of echoes are extracted in the receiver.
Such a problem can be solved by band-pass and low-pass filters.
But the amount of operation by this way is too large for real-time realization.
Thus this paper presents the technique of channelized receiver based on multiphase filter and the receiving schemes of echo.
The proposed receiver has a smaller amount of operation compared to low-pass filter.
At last, the feature extraction technology correlation processing and FDWT are introduced.
In order to verify the feasibility of this scheme in multistatic sonar, the extracted features of original echo are contrasted with those of processed echo via simulation.
Simulation results show that the proposed receiver provides considerable performance.
