Sonar systems are used in seabed mapping and charting applications. The real time processing of sonar signals demand very high-speed computations due to the high platform velocity of the sonar systems. Since direct measurement of real phase delay is not a practicable solution in high performance imaging systems, a systematic phase unwrapping process is often employed to compute the phase delay from the wrapped phase values. Real-time computations are difficult to realize mainly due to the incorporation of phase unwrapping process at the front end. In addition, conventional phase ...
