An Innovative Finite Frequency H∞ Observer for Radar Tracking

To address the advanced driver assistant system (ADAS) in practical application with some disturbances, we propose a novel finite frequency H∞ observer-based method in this study, which enables effectively object tracking to restrain the disturbance during middle and low frequency ranges. We first analyze the Radar tracking characteristics. Then, an H∞ observer is established. Based on the H∞ theory and Kalman-Yakubovic-Popov (KYP) lemma, the design criterion of the finite frequency H∞ observer is established by a linear matrix inequality (LMI). Lastly, two real world experiments are given to demonstrate the effectiveness of the proposed method.
