摘要
实际操作中发现,风廓线雷达回波常受到色噪声的干扰。为抑制色噪声干扰,提高风速估计精度,该文提出采用旋转相位的方法。通过理论分析和仿真,发现旋转相位法不仅有效抑制色噪声干扰,同时也增强了有用的风廓线回波。
The echo of wind profiler radar is always disturbed by colored noise.In order to restrain colored noise,and then improve the precision of the estimation of wind speed,a new method named phase-revolving algorithm is present in this paper.Simulated examples are provided to illustrate the performance of this algorithm.
