3.1.2 Chirp Configuration

The chirp properties can be altered depending on the application requirement using the different commands in the configuration file. A few determining factors for a particular chirp profile are: maximum detection distance requirement, power consumption, and performance. For more information on chirp configuration, see the Programming Chirp Parameters in TI Radar Devices and MIMO Radar application reports.
