  Abstract

In this paper, implementations of a long-range underwater acoustic modem platform and a data acquisition application on the implemented platform are described. The implemented long-range underwater acoustic modem platform is composed of an acoustic array sensor used for transmitting and receiving acoustic signal, two transmit amplifier boards for driving the acoustic array sensor, an analog signal processing board, a main control board, a FPGA board, an interface board and a power supply board. The implemented array acoustic sensor has an omni-directional beam pattern in the azimuth direction and operates properly over 5kHz∼8kHz frequency range. The implemented electric boards are installed in a waterproof cylindrical housing. To verify the function of the implemented long-range underwater acoustic modem platform, a data acquisition application is implemented. The implemented data acquisition application is composed of a control and monitoring GUI, a data exchange server and a data acquiring DSP program, and it can repeatedly transmit a signal at 100 kHz sample rate or can save synchronously sampled received signal from 4 acoustic sensors at 100 kHz sample rate. It can be used to improve modem signal processing algorithms with the acquired real-sea data.
