Portable millimeter wave radar 3D imaging using inverse Radon transform

Radar Imaging Technique

Overview

The recent effort shows that the movement of a single transceiver radar system can lead to 3D imaging. A portable millimeter wave radar 3D imaging system is proposed. The range-doppler information can be extracted from the radar raw data, and a further inverse Radon transform can convert the relative velocity projection data and angle vectors into linear Cartesian coordinates, i.e. azimuth and elevation. Compressed sensing techniques are applied to further enhance the imaging quality while reducing data requirements.
