Abstract:

Based on the idea of the minimum connection of clutter spectrum, a comprehensive recognition method of removing ground clutter which was directed against wind profiler radar ground clutter signals under strong wind conditions was proposed in this paper. Compared with the conventional ground clutter suppression method, the results show that this method had better inhibitory effect on ground clutter under strong wind weather condition, the horizontal wind speed was obviously enhanced, compared with ground observation data, radar products tended to true wind speed. Thus, the accuracy and reliability of extracting atmospheric profile data from wind profiler radar were improved, and a good data quality control foundation for the follow-up product development was built.

摘要:

摘要:以杂波谱极小值连线的思想为基础,针对强风天气条件下的风廓线雷达地物杂波信号,提出一种综合识别杂波的去除方法,并与常规的地物杂波抑制方法相比较。结果表明:利用该方法对强风天气下的地物杂波有更好的抑制效果,水平风速得到了明显增强,与地面观测数据相比,雷达产品更趋于真实风速。
