| 摘 要： | 针对气象无人机GPS／DR组合导航的特点，提出了一种利用位置构成的矢量三角形关系进行风场测量的新方法，并提出了单步长风场测量，最后对测量结果进行了仿真，结果表明：采用单步长测量时风速变化频率较高，能够将风场高频信号的变化特点反映出来，测量精度较高，均方差为4m／s。可以作为气象无人机测风的一种新方法。

| Abstract: | Based on the features of GPS/DR integrated navigation system in meteorological UAV,a new method for measuring the wind field is put forward in this paper,which uses the position relationship between the composition of the vector triangle,and the single step wind field measurement method is presented too.The measurement results are simulated and show that the method can measure the high frequency signals of wind field information accurately,and the measuring accuracy can reach 4m/s.So this method can be used... |
