摘　　要：为了消除测距定位追踪活动目标的测量误差,通过利用四个移动传感器感知活动目标M,由任意三个传感器所得的信息计算出目标M的位置分别为M1、M2、M3、M4,由其四点所围成的凸区域的形心或其所围成的凹区域的主骨架线中点M′作为逼近点替代目标M,从而消除由测量引起的误差。在MATLAB环境中进行仿真实验,表明用四个移动信源节点追踪活动目标M的方法可消除测量误差,M′成功逼近目标M。In order to eliminate measurement error of tracking moving target location, firstly, this paper employed four mobile sensors to detect moving target M. Secondly, calculated the separate locations Ml , M2, M3 , M4 of the target M by information obtained from any of the three sensors, lastly, treated M＇, which was the centroid of convex region or main framework core of concave region surrounded by four points, as approaching point to substitute target M. It carried out simulation test in the MATLAB, the results show that the method of tracking the moving target M by four mobile source node can eliminate measurement error, M＇ approaches target M successfully.
