| Abstract: | Both in China and abroad, there exists an urgent need to develop a real time processing system for underwater wide band signal processing. We design a real time system based on the high performance DSP TMS320C80, whose highest speed is 4 billion operations per second. Our system contains two modules: (1) a module used to sample multi channel analogue signals and also used as a master module to monitor the whole system; (2) a digital signal processing (DSP) module for performing all DSP tasks. Our real time processing system proved successful when applied to BF (beam forming) processing (Fig.5) and DOA (direction of arrival) processing (Fig. 6) of underwater wide band signals. |
