A 220 GHz 3D imaging radar with sub-cm3 voxel resolution for security applications

Radars operating at high millimetre and sub-millimetre wave frequencies are promising candidates for security applications such as people screening since they offer the possibility to form 3D images through clothing with sufficient resolution to detect concealed objects. High spatial resolution of order 1 cm can be achieved using practically sized antennas and high range resolution can be achieved using wideband FMCW chirps, e.g. 30 GHz, to yield 0.5 cm range bins. We present a 220 GHz test-bed ‘Pathfinder’ radar which achieves sub-cm3 voxel resolution with very high signal fidelity. The radar is used to de-risk technology under development for next generation people screening systems.
