Abstract

This paper presents a distributed radar system architecture designed for sensing applications above 100GHz. The proposed radar system leverages high-gain lens arrays to generate extremely narrow beams, enabling high angular resolution. A hybrid beamforming approach is proposed in both the transmitter and receiver arrays, allowing for continuous scanning across a moderate field of view. Additionally, an ideal estimation of radar range is conducted assuming a simplified radar equation for this architecture, showing its potential to detect targets at very long distances.
