摘要
为了弥补激光测风雷达风场反演速度方位显示法的不足、提高反演风速精度,提出了一种改进的方法。运用迭代预处理的方法提高原始雷达数据质量,消除小幅值风速和奇异点的影响,用统计求和平均的方法反演出3维风场;并建立了风场模型,通过数值计算软件进行了仿真和误差分析。结果表明,改进的方法反演出风速的误差不超过0.5m/s,比传统速度方位显示算法的精度提高了1倍。
In order to remedy the shortage of the lidar velocity azimuth display （VAD） method and improve the precision of the inversion wind velocity, a new technique was put forward with iterative pretreatment to eliminate low and oddity wind velocity and with the summation average statistical method to obtain three-dimension wind field. The wind field model was built, and then the simulation and error analysis were carried out. The results show that the absolute error of inversion wind field is within 0.5m/ s, only one half of that of traditional velocity azimuth display method.
