A Template Matching Method of Wideband Sonar Detection

摘要：

Advances in computer memory, computation speed, and transducer bandwidth have made possible, higher Time-Bandwidth product (TB) transmit signals and will bring out higher resolutions. In this paper a new method is proposed to estimation Doppler velocity base on correlation analysis and mode matching in wideband condition instead of wideband matched filter. Paper use mode-matching principle to search appropriate scaled factor matrix.Simulation showing this method has well restrains noise capability and perfect calculation stability; the amount of compute can be decreased greatly by scaled factor matrix computed in advance.
