Design and Test on Acoustic Device for Actively Measuring Underwater Short Distance with High-Precision

For short-distance ranging and positioning of moving targets in water, a design scheme was proposed for active ranging acoustic device based on DSP as the signal processor, and the design ideas of each hardware component were described. The experimental test results of the active ranging acoustic device sample in pool and lake prove that the system is compact in structure, flexible in operation, and has high-precision ranging capabilities, which can meet the needs for short-range ranging applications of moving targets in the water.
