Abstract
Acoustic lens design is proposed for the fabrication of underwater sonar systems for target acquisition. Building upon the vast knowledge of earlier acoustic lens research, the proposed study emphasizes the system integration with the objectives of compactness - both in size and weight, high performance - enhanced data processing speed and image refresh rate, high resolution, low power consumption, and low cost. In particular, DSP (Digital Signal Processor) technology will be used to improve data processing speed, freeing the computer system for other advanced data analysis and system control to improve user-friendliness. Light-weight and low-power display unit will be used to reduce size, weight and power consumption, and more efficient power supply module with be integrated to the system to further conserve power usage and extend the service duration. Finally, human factors will be incorporated into the system design of both software and hardware integration by evaluating users' reports from divers and ROV operators. Anticipated Benefits: The results from this research will provide the critical information for achieving the goal to produce a compact and high performance underwater target acquisition system at an affordable cost. The development is especially useful for mine warfare and other naval or civil operations in shallw water. The technology can be applied equally well for diver-held system or as a part of the underwater vehicles (ROV and AUV).
