Terahertz inverse synthetic aperture radar
(ISAR) imaging with a 
quantum cascade laser transmitter

Optics Express, 2010
A coherent transceiver using a THz quantum cascade (TQCL) laser as the transmitter and an optically pumped molecular laser as the local oscillator has been used, with a pair of Schottky diode mixers in the receiver and reference channels, to acquire high-resolution images of fully illuminated targets, including scale models and concealed objects.
