射电阵列，采用造价低、全天候观测的射电天线，可以建造大面积的观测阵列，达到极高能中微子天文学和极高能宇宙线探测所需的高灵敏度。计划中的巨型天线阵列GRAND，将是世界上10^17eV以上最灵敏的高能中微子望远镜，可以对高能中微子进行有效的观测。原型阵列GRAND-proto中射电天线阵列与闪烁体探测器阵列已经开始联合运行。本项目将利用GRAND-proto复合阵列产生的数据，开展射电探测宇宙线的数据分析，研究背景噪声的排除技术、射电信号的极化特征，挑选出宇宙线事例并研究射电探测宇宙线的重建方法。此外，还将把实验数据与射电模拟数据结合起来，进一步完善空气簇射的射电辐射模型。该研究成果将对国内射电探测宇宙线的数据分析及理论模型工作有重要促进意义。

The radio antenna has the advantage of both low cost and nearly 100% duty cycle, which is suitable to build large area detection array to observe extremely high energy neutrinos and cosmic rays. The prospective giant radio array GRAND will be the most sensitive array for the ultra-high energy neutrinos, above 10^17 eV in the world. Currently a combined radio and scintillator prototype array, called GRAND-proto, is under operation at Tianshan, Xinjiang Province. .In this project, we are going to make full use of the GRAND-proto array to carry out the research of the data analysis of radio signal. We mainly focus on the technique of the exclusion of background noise, the pick out of cosmic ray events according to polarization character of radio signal and the reconstruction of primary cosmic rays. Furthermore, the research devotes to improve radio emission model of air shower according to current experimental data. The research aims to promote the data analysis method and theoretical model of radiation from extensive air shower.
