Reweighting Interacting Multiple-Model Algorithm to Overcome Model Competition for Target Tracking in the Hybrid System

The vicious competition of interacting multiple-model (IMM) algorithm is an inherent problem and would produce irreversible effects on IMM estimation results, especially combining with the radar system. In this article, a novel reweighting IMM (RIMM) is proposed to overcome this issue. First, the theoretical lower bound of model numbers in different situations is respectively provided through the analysis of IMM limitations. Furthermore, …
