A Nonparametric Regularization for Spectrum Estimation of Time-Varying Output-Only Measurements
In this work, an advanced 2D nonparametric correlogram method is presented to cope with output-only measurements of linear (slow) time-varying systems.The proposed method Saute Pans is a novel generalization of the kernel function-based regularization techniques that have been developed for estimating linear time-invariant impulse response function
