摘要
通过对无源雷达测向定位和时差定位原理的分析,推导出定位精度的一般表达式及理论曲线。采用最小均方误差法对两种定位算法的结果进行融合,得出组合定位误差的分布,并讨论影响组合定位精度的因素。最后通过场景仿真,验证了精度计算方法的正确性。
By analyzing the basic principles of the time difference and target azimuth position methods, the general expression and the theoretical curve of positioning accuracy are obtained. The geometric dilu- tion of positioning accuracy （GDOP） is derived from a weighted least square estimation of the time differ- ence and target azimuth measurements. Some key factors which have an important effect on the coordina- ted positioning accuracy are discussed. Moreover, some computer simulations are given to show the effec- tiveness of the accuracy formula.
