2.2 Design Considerations

In TX beamforming, beamsteering, and multiple-input, multiple-output/single-input, multiple-output (MIMO/SIMO) use cases, the larger number of antenna elements allows for higher signal-to-noise ratio (SNR) and superior angular resolution compared to a single-device sensor.

This application focuses on corner and front long-range radar systems for multiple functions such as adaptive cruise control (ACC), automated emergency braking (AEB), blind spot detection, front cross-traffic assist, and lane change assist. The design also demonstrates the TI compression engine and hardware accelerator (HWA) capabilities.

The Cascade Radar evaluation board, when combined with a compatible host/data capture board, contains everything needed to start evaluating a single-device, or 2-device cascaded radar solution.
