摘要
风廓线雷达是用来探测大气风场信息的探测设备,近地面高度回波易受地杂波的干扰,大风天气状况使得气象回波信号很难辨别。为了有效识别气象信号,提高风廓线雷达的探测精度,对风廓线雷达进行地物杂波抑制是雷达数据处理中十分重要的一步。通过研究风廓线雷达回波信号的谱特征,结合常规去地物杂波的方法,提出了基于极小值去地杂波的目标综合识别方法。实际应用表明,该方法在大风条件下对地物杂波去除上是有效的,风场数据得到明显改善。
The wind profile radar is used to detect the atmospheric wind field information detection equipment,The radar e- choes near the ground is vulnerable to the interference of ground clutter and hard to discern in the windy weather condition. In order to identify meteorological signal effectively, ground clutter suppression of Wind Profiler Radar is an important step in radar data processing. By studying the wind profile radar echo signal spectrum characteristics, combined with the conventional method to suppress clutter, the comprehensive identification method based on minimum method to suppress ground clutter is designed. The experiment and application show that this method is effective for removing clutter under the condition of strong wind, and dramatically improve wind field data.
