Paper Abstract
This paper presents an exploratory attempt to use high-resolution radar measurements for face identification in forensic
applications. An imaging radar system developed by JPL was used to measure a human face at 670 GHz. Frontal views
of the face were measured both with and without a ski mask at a range of 25 m. The realized spatial resolution was
roughly 1 cm in all three dimensions. The surfaces of the ski mask and the face were detected by using the two
dominating reflections from amplitude data. Various methods for visualization of these surfaces are presented. The
possibility to use radar data to determine certain face distance measures between well-defined face landmarks, typically
used for anthropometric statistics, was explored. The measures used here were face length, frontal breadth and
interpupillary distance. In many cases the radar system seems to provide sufficient information to exclude an innocent
subject from suspicion. For an accurate identification it is believed that a system must provide significantly more
information.
