应用多普勒技术测量载机速度的原理

The Principle of Measuring Airborne Velocity Using Doppler Technology

分析了影响多普勒技术测速精度的各种因素，认为地球自转是影响最大的因素。若要高精度地测出载机速度，则必须对其进行补偿。

Several affecting factors in measuring airborne velocity accuracy using Doppler technology are analyzed in this paper. It is determined that the rotation of the earth is the most important affecting factor. Thus, it is necessary to compensate the factor for high accuracy of measuring airborne velocity.
