| 摘 要： | 风廓线雷达是探测大气风场和湍流的有效工具,其回波易受地物杂波干扰,使得雷达回波谱变得复杂,为了提高雷达探测精度,地物杂波抑制是风廓线雷达信号或谱处理重要的一部分.介绍了一般地物杂波抑制方法并分析其不足,研究了频域中地物杂波和雷达大气回波谱特征,结合大气回波谱倾斜度分析,提出了基于未受污染大气回波谱高斯最小二乘拟合地物杂波抑制方法,研究表明,该方法在地物杂波抑制处理上是可行的.

| Abstract: | Wind profile radar is an effective tool for detecting atmospheric wind field and turbulence.Its echo is liable to be interfered by ground clutter and becomes complicated.To improve detection precision of radar,ground clutter suppression is an important part of radar signal and spectrum processing.Current method of ground clutter suppression is introduced and its deficiency is analyzed,and the characteristics of ground clutter and radar atmospheric echo spectrum in frequency domain are investigated.Combined ... |
