The Hardware Plan Of One Bathymeter System

Multi-beam swath bathymeter is a kind of equipment for the seabed terrain survey with high efficiency, high precision, and high resolution, especially fits for the wide sweep mapping. With the developing of science & technology and the changing of market's demand, miniaturization of multibeam bathymeter has already become the trend of this field at present. On the basis of our first multi-beam swath bathymeter and referred same foreign products, this thesis proposes the design project for miniaturization.In this thesis, the main task is the design of shallow water multi-beam bathymeter's transmitter and receiver. It includes the primary work of the principle research for multi-beam bathymeter, the calculating of performance's specifications and the choice reason of the detail analog and digital circuits.The hardware platform was designed in this thesis, which is used in the system's transmitter and receiver. The techniques named directly digital synthesizer in details, which is used in the chip of DDS, Class D power amplification and beam-forming based on resistance-phase-shift network is applied. It's analyzed that the method of how to get an easy powerful way of testing the products, and give some suggestions on the experiment design at last.
