An Application of Cepstrum Processing to Active Sonar
1971
Shooter, Jack A. | Senterfitt, Rodney E.
The use of cepstrum is investigated as a means of detecting a target and estimating target length in a low signal to reverberation ratio environment. A model experiment was performed in a fresh water lake using a scale model submarine for a target. The reverberation in the experiment was due mainly to the sound backscattered from the air-water interface. A major result is that the cepstrum output may be averaged from ping to ping to achieve a processing gain, resulting in a higher probability of detection.
