微波辐射计探测大气剖面的相关向量机算法

Retrieving atmosphere profiles by microwave radiometer based on RVM

提出了利用地基双通道水汽微波辐射计探测大气水汽、温度和折射率剖面的相关向量机反演算法,基于青岛地区的历史探空数据和仿真得到的双通道水汽微波辐射计亮温训练了相关向量机网络。青岛地区的实验和仿真比较表明:相关向量机反演得到的剖面与实际大气剖面有较好的一致性。

Based upon relevance vector machine （RVM）, the technique of retrieving atmospheric profiles including vapor, temperature, and refractivity by Ground- based dual-channel vapor radiometer is developed herein. The RVM net is founded on the historic radiosonde profiles in Qingdao and the bright temp of radiometer, which are obtained by simulating from historic radiosonde data. The experimental results and simulation in Qingdao show that this method can obtain good agreement with radiosonde profiles.
