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。The three-dimension problem of space is converted into two-dimension problem of plane by use of plane relation of bistatic radar. Using the rational Supposition for Taylor expansion of locating equation, the authors build up the error analysis model of cross locating algorithm for radar direction finding on the basis of analysis for factors influencing locating accuracy ,and prove that the minimum mean square deviation estimation of space position of locating algorithm is unbiased. The simulation result demonstrates that this error model conforms to the actual sistuation.
