An FM-CW radar module with front-end switching heterodyne receiver

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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
