IMM tracking of a 3D maneuvering target with passive TDOA system
Ling Chen, Shaohong Li · 2003
In recent years, passive localization and tracking are widely studied. Passive Time Difference Of Arrival (TDOA) system is one of important passive location systems. The IMM algorithm is a promising algorithm for tracking maneuvering targets. Here, a new application of IMM tracking algorithm to passive TDOA system is studied. The good tracking performance can be achieved if the accurate target motion models are selected. The paper presents a hybrid model of target motion, called CV-Singer model. Compared with the single model filter and the IMM filter used CV-CA model, the IMM filter used CV-Singer model can provide better tracking performance for passive TDOA systems.
