Short range radar reference design for automotive applications

The TIDEP-0092 from Texas Instruments provides a foundation for a short range radar (SRR) application using the AWR1642 evaluation module (EVM). This design allows the user to estimate and track the position (in the azimuthal plane) and the velocity of objects in its field of view up to 80m.

Autonomous control of a vehicle provides quality-of-life and safety benefits in addition to making the relatively mundane act of driving safer and less difficult. The quality-of-life features include the ability of a vehicle to park itself or to determine whether a lane change is possible and provide features like automatic cruise control—where a vehicle maintains a constant distance with respect to the car ahead of it, essentially tracking the velocity of the car in front of it. 

Autonomous breaking and collision avoidance are safety features that prevent accidents caused by driver inattention. These features work by observing the area in front of a car and alerting the autonomous driving subsystems if obstacles are observed that are likely to hit the car. Implementing these technologies require a variety of sensors to detect obstacles in the environment and track their velocities and positions over time.
