Particle Filter Based Track Before Detect Method for Space Surveillance Radars
Rajat Awadhiya · 2022 IEEE Radar Conference (RadarConf22) · 2022
Space surveillance radars deal with targets posing high range migration and low signal to noise ratio, making them difficult to detect and track. This paper illustrates a particle filter based track before detect approach using coherently integrated target reflections. The method not only tracks the target but also gives the probability of the presence of a target in a given frame. The paper also presents a feedback-based weight update approach to particle filtering, discusses its performance and the potential advancements of this research.
