Abstract:
With the rapid development of information science and electronic technology, sound equipment, aviation has gradually realize systematization and digital sonar system. As the most important part of the sonar system, signal processor processing power have also been more and more attention, on the basis of relevant theoretical research, this paper completes the hardware implementation and software design of the signal processor, and the system debugging. The main research contents include: 1. Introduces the main ways of working, passive sonar, the beamforming, detection and direction finding relevant theory is discussed in detail, and a simulation was carried out. 2. The new sonar signal processor to achieve the function, based on the new DSP devices are discussed the feasibility of a new signal processor and real-time, and completed the design of the new signal processor. 3. According to the characteristics of the new DSP device, its hardware realization and the corresponding software design is given. On this basis, the system debugging, verify the validity of the scheme, and on the basis of debugging scheme for the further improvement.
