摘要
三角定位测量参数选择是设计三角定位方程的基础。三角定位测量参数集(β1,ε1,β2,ε2)分别对应两部雷达测量目标的方位角、高低角。根据测量参数能够建立4个目标位置参数方程,而空中目标位置参数(x,y,z)只有3个,所以存在测量参数冗余。本文在解决三角定位测量参数选择问题上,采用对每种测量子集下的几何关系方程泰勒展开建立协方差矩阵,并运用仿真手段,分析各个测量子集几何定位的优劣,进行综合选择,最后给出应用意见。
The parameter choice of triangular orientation measurement is the base for the design of triangular orientation equation. The measuring set of triangular orientation measurement （β1,ε1,β2,ε2 ） corresponds to the azimuth and the elevation of two radars＇ measurement goals. According to the measurement parameters, four aim＇s location parameter equation can be built, however, the aerial targets＇ location parameter （x, y, z） only have three, so the phenomena of measurement parameters redundancy is existed. By using the Talor Series to build covariance matrix for the geometric equations of every subset and making advantage of ernluator to analyses the good and bad points of each measurement subset geometric orientation, the comprehensive choice in solving the problem of parameter option is fulfilled, and at last the application views are given in this paper.
