Abstract :
The authors have developed a 60-GHz FM-continuous wave (CW) radar module that generates sidebands by switching a high electron mobility transistor (HEMT) front-end. The module also uses heterodyne detection for FM-AM conversion noise reduction. The module´s signal to noise ratio was 20 dB better than a previously designed homodyne FM-CW radar module.<>
