Abstract

This document was translated from a simplified Chinese source. (ZHCAG89)

The AWR2x44x series SoC is specifically designed for ADAS millimeter-wave radar. To address challenges such as temperature drift, device aging, and electromagnetic interference, the system introduces runtime calibration and real-time monitoring mechanisms. Runtime calibration dynamically compensates for RF link deviations to ensure stable radar operation within the range of -40℃ to 140℃; the monitoring module continuously tracks key metrics based on Built-In Self-Test (BIST) and issues timely alerts upon anomalies. Combining the AWR2944P OOB example, this paper introduces relevant API configuration methods, execution time calculation examples, and parameter setting precautions, providing a reference for the reliability design of radar systems.
