摘要

根据宽带水声信号的特点，提出了一种基于梅林变换的宽带模糊函数求解方法，研究了基于快速梅林变换算法的宽带信号处理。理论分析和仿真结果表明，对于宽带水声回波信号，该算法具有计算效率高、宽带模糊函数聚集性好等特点，具有一定的应用价值。

Abstract

According to the features of wideband underwater acoustic signal, a solving method of wide-band ambiguity fuction 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.
