英文摘要：

A passive acoustic localization system is designed that is centered on TMS320F2812 digital signal processor in base of cross correlation time delay estimating algorithm. Using its owing characteristic of both digital signal processor and micro-controller, the chip structure design is simplified and systematic processor ability is improved. A target localization is realized on the basis of accomplishing muhi-path audible signal synchronous acquisition, storage and data processor. The result indicates by measurement that system in distance of 25 m×25m in the fiat surface range, target localization time is within 2 s and angle error is smaller than 2.7 % , reaches the real time target localization.
