Concealed threat detection with the IRAD sub-millimeter wave 3D imaging radar

Autor: Scott L. Cassidy, Ben Jones, Duncan A. Robertson, Anthony Clark

Publikováno v: SPIE Proceedings.

Sub-millimeter wave 3D imaging radar is a promising technology for the stand-off detection of threats concealed on people. The IRAD 340 GHz 3D imaging radar uses polarization intensity information to identify signatures associated with concealed thre

Micro-doppler and vibrometry at millimeter and sub-millimeter wavelengths

Autor: Scott L. Cassidy, Duncan A. Robertson

Publikováno v: SPIE Proceedings.

Micro-Doppler is an emerging technique for the measurement and analysis of target modulation characteristics, rooted in the analysis of X-band radar measurements of people. Despite the advantage of higher Doppler sensitivity, there appears to be litt

340-GHz 3D radar imaging test bed with 10-Hz frame rate

Autor: Robert J. C. Middleton, Duncan A. Robertson, Scott L. Cassidy, David R. Bolton, Peter J. Speirs, David G. Macfarlane, Paul N. Marsh, Robert I. Hunter, Graham Smith

Publikováno v: SPIE Proceedings.

We present a 340 GHz 3D radar imaging test bed with 10 Hz frame rate which enables the investigation of strategies for the detection of concealed threats in high risk public areas. The radar uses a wideband heterodyne scheme and fast-scanning optics
