| 摘 要： | 利用双基地平面关系将空间三维问题降为平面二维处理;在分析影响定位精度因素前提下,采用合理的假定对定位方程泰勒展开,建立测向交叉定位算法的误差分析模型,并证明了测向交叉定位算法的空间位置最小均方差估计是无偏估计,通过仿真算例,可以看出建立的误差模型符合实际情况。

| Abstract: | Through makeing use of bistatic radar direction relationship on a plane we reduce the three-dimensional problems to the two-dimension ones to handle.Under the condition of analysis of position locationing accuracy,we use a taylor expansion to establish the error model of azimuth and elevation measurement,and we prove that the estimation of azimuth and elevation has no biased error.With a calculated simulation example,we can see that the established error model conforms to the actual circumstance. |
