摘要
摘要:本研究主要利用张衡一号电磁卫星(CSES)记录的电磁场波形数据,研发了电磁波波矢量分析工具,该工具包提供电磁波形频谱变换、奇异值分解(SVD)方法以及坡印廷能流计算功能.选取了张衡一号卫星在ULF/ELF/VLF频段观测到的哨声波、准周期辐射、电离层嘶声波等典型波动事件,开展了频谱分析和波矢量分析.通过与DEMETER卫星的对比观测研究,验证了算法的正确性,并且初步探讨了这些波动的传播特征,其结果也验证了张衡一号卫星在电磁场观测方面具有良好的性能.本研究研发的波矢量分析工具包可直接运用到张衡一号卫星的常规数据处理和科学分析应用中.

Abstract:This study mainly developed a wave vector analysis tool for the electromagnetic waves recorded by the China Seismo-Electromagnetic Satellite(CSES), which provides the functions of waveform spectrum transform, singular value decomposition (SVD) and Poynting flux methods. According to the typical electromagnetic wave events recorded by CSES satellite, such as lightning induced whistler-mode waves, quasi-periodic emissions, ionospheric hiss waves, we applied the tool to analyze the propagation feature of waves and preliminarily discussed the spectral features and propagation parameters of these waves. We also validated the algorithm code by comparison with DEMETER's observations, and results confirm that the CSES has good performance on the electromagnetic field observations. The wave vector analysis tool developed in this study can be directly applied to the routine data processing and scientific application of CSES satellite.
