Experimental study of external interference mitigation for LEO based sensing (AIS)

Abstract

Satellite Automatic Identification System (SAT-AIS) are corrupted by spike noise interference from the ground radar site on any area, and trajectory conditions and median filtering algorithms are becoming essential for detail analysis. To facilitate the introduction of such techniques into the satellite mega-constellations, we evaluate effective conditions of the spike noise filtering for trajectory area and sea area and give an introduction to the experimental result from SPace based AIS Experiment (SPAISE2) mounted on the Advanced Land Observing Satellite-2 (ALOS-2).
