Abstract :
In this contribution we compare two different techniques to perform a range refocusing from 12.5 m to 37.5 m in a Terahertz Imaging Radar. The first technique, already verified experimentally, consists on the mechanical translation of the transceiver, whereas the second technique consists on the deformation of a membrane mirror with the potential to achieve larger refocusing speeds.
