摘要：The multi-beam sounding technology has been carrying out a revolution in underwater survey. Compared with traditional equipment's, the multi-beam sounding system has a huge advantage in efficiency, accuracy and resolution. According to the beam-forming theory, the paper designs a phase-control signal formulation circuit based on FPGA (Field Programmable Gate Array), and the experiments show that the multi-beam transmitter has a high performance and can fully meet the needs.
