Abstract
Screening crowds for threats requires a stand-off sensor with wide area coverage, high spatial resolution and a high temporal update rate. We have assessed the capability of the NIRAD high speed 94 GHz FMCW surveillance radar against this requirement. NIRADas sub-degree beamwidth, 25 cm range bins and 10 Hz azimuthal frame rate yield high resolution radar videos of scenes over ranges from tens to hundreds of meters, capable of tracking people walking or running around the scene. We present how people are detected and tracked in the scene to enable analysis of their radar cross section images to reveal signatures which may indicate the presence of a carried threat item.
