| 摘 要： | 为实现对静/动目标的有效定位,推导出定位精度的几何稀释（Geometric Dilution of Positioning Accuracy,GDOP）的协方差矩阵计算公式和GDOP的影响因素。利用时差和目标方位角对静/动目标进行定位的基本原理,可得到定位精度的一般表达式及其理论曲线,以及其目标和接收机之间的相对几何关系与测量误差的关系,可有效实现对静/动目标的定位。

| Abstract: | The computing formula of the covariance matrix of GDOP(geometric dilution of positioning accuracy) and the factors influencing it are derived by using time difference and target azimuth to analyze the basic principles and positioning accuracy for positioning the static/ moving targets.Using TDOA position method,the general expression and the theoretical curve of positioning accuracy,as well as the relation between the measurement error and the relative geometrical relation between the target and the receive... |
