Angle Only Tracking for Infrared Search and Track (IRST) System Mounted on an Aircraft

This paper presents an interactive multiple model (IMM) based angle only tracking approach with global nearest neighborhood (GNN) data association algorithm for infrared search and track (IRST) system mounted on an aircraft. Two target motion models are considered in IMM namely, Constant Angular Velocity (CAV) model and Constant Angular Acceleration (CAA) model. Simulation scenarios are generated with targets maneuvering and detected by an IRST in track while scan (TWS) mode of operation. Performance of the proposed algorithm for tracking multiple maneuvering targets with IRST in TWS mode is presented in this paper.
