AWR1843AOP: Changing the start frequency of the Radar

Matina Rahbar

Part Number: AWR1843AOP

Tool/software:

Hello,

I am trying to change the start frequency of the radar sensor. The range is 76GHZ - 81 GHZ , and I change the start frequency in the profile configuration and I launch the data collection process through ROS, and it launches a visualizer (RVIZ) that displays all of the point clouds that the sensor is detecting. However, once I change the start frequency above 77GHz I get an error and I can't see the point clouds. Could someone help me in changing the start frequency above 77GHz please.

Hi,

You should be able to change the start frequency however you need to make sure that the bandwidth used does not exceed max freq. 81 GHz.

Thank you

yeah i am trying to change it between 76-81GHZ but I keep getting errors. I am changing it in the configuration file (.cfg) is that the right way of doing it?

Can you please share the configuration file you are using?

You will also need to modify the bandwidth of the chirp if it extends beyond the max 81Ghz

Thank you
