doi:10.11947/j.AGCS.2015.20140345

Abstract

Abstract: A robust ridge estimation multi-source data fusion algorithm is proposed based on spherical cap harmonic analysis.The effectiveness is verified through numerical calculations. It is shown that this fused model can not only resist the ill-conditioning of coefficients array but also eliminate the observation errors. Finally, it is analyzed the influence of the observation noise size on the fusion results.

Key words: pherical cap harmonic analysis, least squares, robust ridge estimation, spherical harmonic model, boundary effect
