摘　　要：时间差无源定位技术(TDOA)是目前无线电定位技术中切实可行且精度较高的定位体制,得到了广泛关注与研究。而定位算法的选择决定了TDOA技术是否能顺利应用于实际工程并满足其需求。通过对常见的定位算法进行比较,选择概率定位算法应用于实际工程,设计开发了一个具有完整定位功能的测试平台,并已成功应用于无线电网络监测系统。The TDOA location technology has attracted widely interest and research since it is a viable and high- precision location System. However,whether it can be applied in practical project successfully and adequately depends on selection of location algorithm. By comparing several common location algorithms, selecting probability location algorithm for practical application. In addition,a testing platform which is provided with the integral location function is designed and developed and has been successfully applied in the wireless monitoring system.
