Fusion of Radar and Communication Information for Tracking in OFDM Automotive Radar at 24 GHz

In this paper, a novel method for tracking targets using OFDM radar with an integrated communication system (RadCom) for automotive applications is presented. OFDM-based radar schemes are promising candidates for future intelligent transportation networks. However, due to system resolution limitations, improvements in estimation and tracking of targets are required. Correct and accurate object tracking is a critical aspect of advanced driver assistance systems. The proposed method takes advantage of the dual functionality of RadCom systems through an information fusion approach that combines the radar signal reflected by the targets with received communication signals. The main idea is to explore cooperation between vehicles to improve safety and accuracy during tracking. Tracking results of laboratory measurements at 24 GHz and simulation results in a multi-target environment are presented.
