Automotive 60GHz 3D Detection model
for In-Cabin Sensing SC1260AR3
SC1260AR3 is an extremely low-power, small size and intelligent all-in-one CMOS 60GHz radar sensor device with AiP(Antenna in Package), available for 3D (including 1D, 2D) sensing, and suitable for in-cabin sensing application.
It contains a high-performance radar signal processing unit and detects the 3D position of moving objects and the presence of the objects in any specific area.
