Key Challenges
Designers at VTT Technical Research Centre of Finland Ltd.
(VTT) were tasked with developing a 60GHz frequen-
cy-modulated continuous wave (FMCW), frequency-division
multiplexing (FDM), multiple-in-multiple-out (MIMO) radar
system for short-range, high-resolution detection of nearby
moving objects when the radar itself might be moving, in
order to capture the flow of people, drones, and other
autonomous systems. In addition, the system supports
simultaneous localization and mapping, object detection,
and remote multi-target vital sign measurements for
medical applications. An FDM MIMO architecture was
chosen to address the technical requirements for fast
imaging and high resolution of multiple targets. Using MIMO
techniques, 64 virtual channels were synthesized with only
eight RX and eight TX channels (Figure 1), thereby signifi-
cantly reducing the number of physical elements. This
greatly reduces the system complexity, size, and cost.
