A kind of seafloor small target close detection system and its ex-perimental research
英文摘要：With the development of underwater-vehicle technology and the demand of detection of mines on special occasions, the method of seafloor small targets' detection, based on underwater small platforms, is becoming more and more popular. This paper, according to the theories of parametric emission array, combining the advantages of parametric array and the characteristics of cut-off parametric array, designed a kind of near detection system applying to seafloor small targets, did a series of experiments to test this system's characters in near range and carry out sink and buried targets. The results showed that, this parametric array detection system can achieve seafloor small targets' near detection, the exploring work under the existing conditions will increase some reference value in engineering.
