摘要：

Frequency Modulated Continuous Wave (FMCW) radars are part of the new sensing devices installed in vehicles in order to explore the surroundings. Millimetric wave (mmW) frequency bands provide enough information to apply imaging algorithm. The Multifrequency Bifocusing (MFBF) imaging algorithm in the W-band using FMCW radar has a direct applicability in enhancing detection of concealed weapons, as proximity sensors to avoid collisions and pedestrian detection in vehicles. This paper assesses the feasibility of using the Intermediate Frequency (IF) signal provided by homodyne FMCW radar operating in 77 GHz as input to the mmW MFBF monostatic-bistatic algorithm from a theoretical point of view and by means of simulation. MFBF algorithm results using FMCW radar are compared with that obtained using FSCW, equivalent to the parameter S-21 obtained from a Vector Network Analyzer (VNA). (C) 2020 Elsevier GmbH.
