摘要
针对航空物探中高精度航磁补偿的要求,概述了航空平台磁干扰模型的建立过程,推导了16项磁补偿算法的求解过程,分析了其在计算过程中解决复共线性问题时采用的方法,针对该方法存在的问题,提出了用岭回归法来改进的方案,并用实验验证了改进效果。
According to the requirements of the high precision magnetic composition in airborne geophysical prospecting, the paper overviews the process of building the magnetic interference model, deduces the calculation process in detail of the 16 terms magnetic compensation algorithm, and analyzes the method which the algorithm uses to solve the muhicollinearity of the equation. Furthermore, aiming at the problem in the method, the paper proposes ridge regression method to improve the program, and verifies the improved result with experiment.
