Studies of Polarimetric Signatures in Winter and Spring Time Storms Using the CSU-CHILL Radar

利用CSU-CHILL雷达研究冬季和春季风暴的极化特征本研究的目的是利用CSU-CHILL雷达研究冬季和春季风暴的极化特征。将特别强调基于神经网络/傅里叶描述符的图像分类技术，以处理水陨石的2D-PM图像，以便与偏振特征进行现场比较。观察了CSU-CHILL雷达新的高性能低旁瓣天线系统对极化特性研究的意义。将研究极化雷达特征信号的空间和时间演变，以求在几个水流星习惯区建立平均特征信号。多维参数集将用于水流星和降水类型的分类。总体目标是研究极化雷达信号的应用，以研究冬季和春季风暴中降水的类型和分布。

Chandra Abstract Studies of Polarimetric Signatures in Winter and Spring Time Storms Using the CSU-CHILL Radar The objective of this research is to study polarimetric signatures in winter and spring time storms using the CSU-CHILL radar. Special emphasis will be placed on Neural network/Fourier descriptor based image classification techniques to process 2D-PM images of hydrometeors for insitu comparison with polarimetric signatures. The significance of the new high performance low side lobe antenna system of the CSU-CHILL radar for studying polarimetric signatures will b observed. Spatial and temporal evolution of polarimetric radar signatures will be studied to develop average signatures in several hydrometeor habit regions. Multidimensional parameter set will be used for classification of hydrometeor and precipitation types. The overall goal is to study the application of polarimetric radar signatures to study the type and distribution of precipitation in winter and spring storms.
