Description

This reference design provides a foundation for corner radar applications to meet NCAP R79 safety requirements using the AWR2944 evaluation module (EVM). The design allows users to estimate and track the position (in the azimuthal plane) and velocity of objects in the field of view of the device up to 200 m. This application focuses on corner and front long-range radar systems for multiple functions such as blind spot detection, front cross-traffic assist, and lane change assist. The design also demonstrates the TI compression engine and hardware accelerator (HWA) capabilities.
