| 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。

| Affiliation: | SONG Wen-bin(The 10th Research Institute of CETC,Chengdu 610036,China) 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 dilution of positioning accuracy(GDOP) is derived from a weighted least square estimation of the time difference and target azimuth measurements.Some key factors which have an important effect on the coordinated positioning accuracy are discussed.Moreover,some computer simulations are given to show the effectiveness of the accuracy formula. passive radar;positioning accuracy;TDOA;GDOP |
