The concept of a flexible system for radar measurements at low terahertz frequencies

In this paper the authors present a concept of flexible system for conducting a wide variety of radar measurements at lower terahertz band (75-500 GHz) along with its laboratory implementation. The presented system comprises four main parts: a motorized measurement table, a modular analogue intermediary block as well as recording and signal generation hardware and software. A design of the commercial-off-the-shelf (COTS)-based system built in the Radar Techniques Laboratory of the Warsaw University of Technology is presented. Preliminary results obtained using the designed system are also introduced.
