摘要
随着水下航行器技术的发展及探雷等特殊场合的需求,利用水下小平台探测海底小目标的方式逐渐受到重视,本文依据参量发射阵理论,结合参量阵的优势、截断参量阵的特点,设计了一种应用于海底小目标近距离探测的系统,测试该探测系统在近距离的特性,进行沉底及掩埋目标的探测实验,结果表明,该参量阵系统能够实现海底小目标近距离探测,在现有条件下所做的探索工作具有一定的工程参考价值。
With the development of underwater-vehicle technology and the demand of detection of mines on special oc- casions, 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 tar- gets, did a series of experiments to test this system＇s characters in near range and carry out sink and buried targets. The res- ults 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.
