Abstract :
The correlation leaking point localization instrument uses the mutual correlation latency estimate to realize the leakage accurate localization. Two methods were designed to realize two sequences´ mutual correlation operations on DSP in this paper. The experimental result indicated that the fast correlation localization algorithm has quicker processing speed in water leakage survey application, but the time domain direct correlation localization algorithm has higher precision.
