基于径向谱的位场向下延拓正则参数选取方法
Keywords: 向下延拓,tikhonov正则,径向平均功率谱,l-曲线法
Abstract:
？tikhonov正则算法是解决位场向下延拓不适定性广泛采用的一种有效方法,最优正则参数的选取对下延精度和计算时间都有影响.为了快速、有效地选取正则参数,提出一种基于位场径向平均功率谱的tikhonov正则参数选取方法.该方法通过建立由径向平均功率谱确定的截止波数和tikhonov正则低通滤波函数的截止波数的关系来确定正则参数.基于理论重力模型数据及航磁实测数据将新方法同以往普遍采用的l-曲线法、c-范数法进行了正则向下延拓效果的对比实验.实验结果表明,新方法实现简单、物理意义明确,且选取的正则参数优于另外两种经典方法.
