摘要
目的:对多普勒雷达原始数据进行预处理。方法:利用K-邻域频数法分析不同参数的选取对于结果的影响,并结合雷达原始资料的实际情况,在参数的选取方法上进行了优化,并用不同的窗口大小去适应不同的区域。结果:在速度退模糊起始点的选择上做了补充,使得去噪补缺的效果更好,速度退模糊的效果大大改善。结论:提出了寻找退模糊起始点的方法。
Objective To pre-process Doppler radar data.Methods K-neighborhood frequency method was used and the influence of different parameter on result was analyzed.Based on radar source material,selection of parameter（K1,K2） was optimized,with proper window size in different area.Results Selection on starting point of velocity dealiasing is supplemented to better denoise effect and improve velocity dealiasing effect.Conclusion Method for selecting starting point of dealiasing is proposed.
