Relationship between length of the chirp and depth of the ocean in active sonar processing

Active sonar is a fairly old area of research in ocean bottom profiling and imaging. A lot of work has already been done related to choice of signal in active sonar which shows that chirp is one of the best candidates. Previous works show that time-bandwidth product of chirp determines SNR and resolution in active estimations. This paper shows that an increase in the length of chirp does not alway…
