| 摘 要： | 研究风廓线雷达风谱的概率分布,对估计噪声水平、评价风谱形成算法的性能、提取风廓线回波的信息等等都有重要的作用和意义.目前,接收机噪声的谱的概率分布得到了较好的研究,而风廓线回波的谱的分布却缺少相应的分析,鉴于此,研究了风谱的概率分布.通过对雷达回波做合理的假设,在分析经典风谱形成算法的基础上,提出雷达噪声谱和风廓线回波的谱分别服从X2,分布和非中心X2分布.利用实际的雷达数据和计算机仿真的方法进行的分布的假设检验,说明该理论模型准确有效.

| Abstract: | The probability distribution of radar wind profiler spectra is very important for estimating the noise level,evaluating the performance of the wind spectra generation algorithm,and extracting the information of atmospheric echo.Until now,the probability distribution of noise spectra is well researched except that of atmospheric echo.Therefore,the probability distribution of wind spectra is researched in this paper.Based on rational hypothesis to the atmospheric echo and noise,and the analysis of the classic... |
