多测向站测向定位的递推模型与算法

讨论了测向定位中的若干问题,包括双站交会定位及其定位误差分析和多站交会定位,首次尝试将最小二乘方法和递推最小二乘方法用于多站测向定位的算法,建立多站交会定位的误差模型,充分运用了多个测向站的测向数据,大大提高测向定位的精度。递推运算省去了大量的矩阵运算和求导运算,简化了工作量。理论分析和实际运算表明,多测向站测向定位的递推模型与算法对于提高测向定位的精度和简化运算量有很大的作用,有相当的实用性。

Model and Algorithm of Location with Multi-DF Stations

This paper discusses some problems about DF and location,including cross location with two stations and anal- ysis of location error,cross location with many stations.Finally we try to use algorithm of LS and recursive LS to cross location with multiple stations,and set up an error model of multiple stations,so as to use DF data of many DF stations fully,thus enhancing precision of DF.Recursion operation saves much matrix and derivation operation,so workload is reduced.Theoretical analysis and actual operation indicate that the model and algorithm of location with multi-DF stations are valid,and the accuracy of DF and loca- tion are improved.
