Near-Field Synthetic Aperture Radar Utilizing a Commercial V-Band MIMO Radar Sensor

Millimeter-wave imaging can provide visibility through multiple materials for security screening, non-destructive testing, and goods inspection. One traditional challenge with millimeter-wave imaging is associated with the high overall system cost due to the need for multi-element apertures. Recent advancements in radar technology have made multiple off-the-shelf radar boards available which can be used for millimeter-wave scanning of goods and security screening. In this paper we discuss a synthetic aperture radar architecture that scans a V-band multiple-input multiple-output (MIMO) radar in a small number of locations in space to synthesize a larger radar aperture. We show experimental measurements using a 20TX/20RX 62–69 GHz MIMO radar sensor.
