  • 摘要: 基于平衡態(tài)非相干散射理論的GUISDAP程序包在擬合含有純增長模式線的非相干散射功率譜及反演加熱擾動電離層參量中存在嚴重誤差,該文提出一種以未加熱時刻的電離層參量為先驗信息,利用最小二乘法搜尋最佳高斯峰描述純增長模式線來修正實測非相干散射譜,并使用電子超高斯分布的非相干散射理論擬合修正后非相干散射譜來反演獲取加熱擾動電子溫度的方法。通過將該方法用于分析2010年秋季我國在挪威開展的電離層加熱實驗數(shù)據(jù)表明:利用該方法對含純增長模式線的實測譜修正擬合后獲得的電子溫度比未加熱時刻提高約800 K左右,增幅比例約13%~50%,該結(jié)果與現(xiàn)有文獻報道的電離層加熱引起的電子溫度增幅范圍吻合較好。結(jié)論表明該方法適用于基于含純增長模式線的非相干散射譜反演擾動電離層參量。
