Wide Band Sonar Signal Processing Based on Wide Band Correlation Ambiguity Function

摘要

With the development of new type of transducer, the available bandwidth of sonar systems continues to expand. Wider bandwidth means more benefits in range and velocity resolution. However, with the expansion of bandwidth, the narrow band condition cannot be satisfied any more, and a wide band signal processing method should be introduced. In this paper, wide band processing method based on wide band correlation ambiguity function is reviewed, and simulation shows the advantages of this method in wideband signal processing, simulation results also show the benefits of extend bandwidth.
