摘　　要：介绍了参量阵理论以及多波束测深系统,提出了一种基于参量阵的多波束测深方法。传统的单波束测深系统每次测量只能获得测量船垂直下方一个海底测量深度值,而多波束探测能获得一个条带覆盖区域内多个测量点的海底深度值。与现有的多波束测深系统相比,采用参量阵的多波束测深技术,很好地增大了探测深度,减小了换能器体积、减轻了换能器重量,而且发射的波束角很小,具有很高的分辨率,可以同时探测浅海区深度和深海区深度,具有较大的应用价值。The design of multi beam sounding system based on parametric array is studied. It belongs to the technical field of submarine reconnaissance. The system uses the parametric array technology, and the transmitter array is two sub arrays. Compared with the traditional single beam echo sounding system, it can only obtain a measurement of the depth of a submarine. The multi beam probe can obtain the depth of the seabed with multiple measurement points within the coverage area and improve the measurement efficiency. Compared with the existing multi beam echo sounding system, the invention uses the parametric array technology, which can increase the detection depth, reduce the volume of the transducer, and reduce the weight of the transducer.
