Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is widely used in modern mobile communications. To compensate for channel effects, known reference signals (pilots) are transmitted, enabling estimation of the Channel Frequency Response (CFR). In Integrated Sensing and Communication (ISAC) systems, the CFR can serve both for data equalization and target detection, as moving objects near the receiver cause oscillations in the Channel Impulse Response (CIR), derived from the CFR. However, due to the sparse placement of pilots, traditional sensing may struggle with accurate detection and velocity estimation, especially for weak or fast-moving targets. In this paper, we propose enhancing OFDM-based sensing by utilizing reconstructed user data in addition to pilot signals to re-estimate the CFR. We demonstrate that this User Data Radar (UD-Radar) approach improves detection of weaker paths and enables more accurate velocity estimation for high-speed targets compared to pilot-only radar (P-Radar).
