中文摘要：

针对风廓线雷达实际应用中,飞鸟等飞行体产生的间歇杂波对风谱识别的严重干扰问题,提出了一种小波系数代换的杂波抑制方法.通过分析风廓线雷达的信号特性,根据间歇杂波的突发性和持续时间短的特点,给出了在小波域内通过非相干谱积累之间信号能量一致性检验的杂波识别方法、判定公式以及相关尺度间小波系数代换的抑制方法.实测数据验证结果表明,杂波抑制效果明显.

英文摘要：

Intermittent clutter produced by flyers such as birds is a severe interference for wind detecting.For resolving the problem of clutter rejection,a method based on wavelet coefficients replacement is suggested. According to the clutter characteristics of the clutter bursting and short duration gained by the echoes analyzing,a novel method for the clutter recognition based on power consistency checking of different spectral integration signals in the wavelet transform domain,clutter discriminant function and clutter suppression method based on counterpart scale wavelet coefficients replacement are proposed.By the data measured from field testing,high efficiency of clutter rejection is verified.
