DENSO Develops New 24-GHz Band Submillimeter-wave Radar Sensor

DENSO Corporation today announced that it has developed a 24-GHz
submillimeter-wave rear and side radar sensor to help enhance
vehicle safety systems. The sensor is used in the 2018 Toyota Camry
released this past July.
It's strategically built into the rear bumper of the vehicle to
detect other vehicles likely to enter the driver's blind spot to
the rear and side, as well as vehicles approaching from the rear on
the left and right when reversing. The sensor is part of a larger
system that helps drivers identify and navigate around other
vehicles when changing lanes or reversing out of a parking space,
and controls the autonomous emergency braking function to avoid
imminent collisions.
To enable accurate detection whether moving forward or reversing, a
phase shifter switches the sensing direction and range of the
submillimeter-wave radar sensor. Radio wave transmission and
receiving, and phase shifter functions also run through separate
integrated circuits (ICs) to reduce the size of the sensor.
In 2003, DENSO became the world's first company to develop and
commercialize an electronically scanning in-vehicle millimeter-wave
radar sensor, which utilized digital beamforming. By advancing
these technologies DENSO continues to deliver on its mission to
build a safe and secure automotive society for all.
