| 摘 要： | 研究了基于低功耗设计的通道预处理模块与TMS320VC5509A构建的低功耗水声被动探测定位系统。系统定位利用较多基元间时延信息，采用互谱定位算法进行目标定位，极大提高了系统定位精度。经某湖声源定位测试，结果表明系统在速度、功耗等方面满足水中被动定位的特殊要求，具有良好的应用前景。

| Abstract: | A new kind of underwater target passive locating system, which consists of ultra-power pre-processing module and TMS320VC5509A, is presented. The location angles are gotten by cross-spectrum method using much more time delay information. And the system gets better locating result than ever got. The experiment results indicate that the whole system can satisfy underwater target passive location in the expects of velocity and power consuming,and that the method is promising. |
