SAR millimeter wave imaging systems

Millimeter wave imaging systems are a promising candidate for many applications, such as indoor security, non-destructive evaluation, and automotive driver assistance. In this paper, we use an automotive radar sensor for imaging applications. We implement mono-static single-input-single-output (SISO) configuration to perform synthetic aperture radar (SAR) measurements. The reconstructed image of a spiral target by using this real imagery SAR system is compared with computational simulation results. We also present SAR measurements on several targets including: a mannequin with a gun for concealed weapon detection; pipes behind a wall for seeing through wall; and range discrimination of multiple objects. Eventually, we propose a volumetric method for data collection for automotive applications.
