Millimetre-wave radar sensor for satellite radar architectures

TI has introduced a millimetre-wave radar sensor chip which it claims to be the industry’s first for satellite radar architectures, enabling higher levels of autonomy by improving sensor fusion and decision-making in ADAS.

In satellite architectures, radar sensors output semi-processed data to a central processor for ADAS decision-making using sensor fusion algorithms, taking advantage of the 360-degree sensor coverage to achieve higher levels of vehicle safety.

The chip, the AWR2544, has launch-on-package (LOP) technology which helps reduce the size of the sensor by as much as 30% by mounting a 3D waveguide antenna on the opposite side of the printed circuit board. LOP technology also enables sensor ranges to extend beyond 200m with a single chip.

In satellite architectures, these features enable automakers to increase ADAS intelligence for higher vehicle autonomy levels to make smarter decisions from farther away.

The AWR2544 is the latest in TI’s radar sensor portfolio, which supports a wide range of ADAS applications and architectures with sensors developed for corner, front, imaging, side and rear radar
