摘要
针对常规武器系统靶场试验中出现的相对坐标转换的需求,提出一种两点间相对位置关系的坐标转换方法。该方法首先建立了两点经纬度转化为相对角度距离的数学模型,然后在此基础上分析了已知武器系统大地坐标和目标相对武器系统角度距离的情况下,通过迭代法解目标大地坐标的数学模型,并采用C++builder编制程序实现转换的自动化和批量化,最后通过大地测量成果点进行数据转换精度的验证。结果表明:该方法计算准确度高,运算速度快,可以解决靶场试验中相对坐标转换问题。
Aim at relative coordinate conversion requirement in the conventional weapon system range test,a coordinate conversion method of relative position relation is put forward between two positions.Firstly,this method built mathematical model that converted geographical coordinate to relative angle and distance between two positions,then based on the model,analyzed weapon system geographical coordinate and relative angle distance between target and weapon system,geographical coordinate mathematical model of target was solved by iterative method.Used C++builder compile program to realize automatic and batch conversion.At last data conversion precision and validity was validated by geographical measure harvest position.The conclusion indicates:this method calculation precision is high,and calculation speed is rapid,it can resolve the relative coordinate conversion problem in range test.
