| Abstract: | According to the features of wideband underwater acoustic signal, a solving method of wideband ambiguity ruction based on Mellin transform was put forward and the wideband signal processing based on fast Mellin transform algorithm was studied. Theoretical analysis and simulation indicate that this algorithm not only implememts efficiently but also has good concentration in wideband ambiguity domain, so it is very suited for online processing of wideband underwater acoustic signal. |

| Keywords: | acoustics Mellin transformation wideband ambiguity function underwater acoustic signal processing |
