Demonstrating the use of a class of min-max smoothers for D-region event detection in narrowband VLF phase
This paper describes the use of a class of non‐linear smoothers for the identification of interesting phenomena in narrowband very low frequency (VLF) transmission phase caused by perturbation events in the D‐region of the ionosphere. The LULU smoothers, named for their smoothing of upward (L) and d...
