摘要
介绍一种利用微型无人驾驶飞机为探测平台，ＧＰＳ接收机为测量装置的解析测风方法。它基于飞机盘旋飞行与大气运动有十分显著的差别，建立运动方程组，用解析的方法求算大气运动。理论分析和与小球及雷达测风的比较都表明，解析测风方法是一种精度较高的测风方法。
An analytical method for wind measurements by an atmospheric sounding mini--aircraft ispresented. The method is based on the fact that the spiral movement of mini-aircraft is controlled bythe automatic navigation system. The synthetic movement (i.e., ground velocity) is detetmined by a GPSreceiver onboard the mini--aircraft. Based on the general motion equations, the analytical formula areobtained to calculate the horizontal componments of the wind speed. Both theoretical error analysis andexprimental measurements in comparison with balloon and radar techniques show that the proposedanalytical method can provide accurate and high resolution profiles of wind velocity.
