The Impact of Automotive Radar Configuration on Power Consumption: The Case of TI AWR1843

The development of more intelligent vehicles needs state-of-the-art detection and vision sensors. These devices are very powerful and in future, they will be used massively to reach full autonomous driving. In addition to being intelligent, the vehicles of the future should exhibit the lowest possible power consumption to minimize their carbon footprint. Radars are essential sensors in intelligent vehicles, they are not new in vehicles but recently have gained new interest thanks to considerably increased performances. To meet both requirements, it is interesting to study the impact associated with the onboard sensors, specifically with an increased resolution and detection performance of Radars. In this study, an analysis of power consumption related to the Radar configuration is proposed. The analysis will show how the configuration affects device power consumption and must be taken into account when these sensors are deployed on vehicles.
