CCS/AWR1642BOOST-ODS: SRR demo velocity estimation issue

Tool/software: Code Composer Studio

I’m trying to work with SRR demo using awr1642boost-ods. The board is in a room which all of the objects are static, but as u can see in Doppler-Range plot it shows that there are obstacles with approximately -11m/s velocity. The configuration is set for USRR (one subframe) which has the maximum range of 20 meters and maximum velocity of 5m/s (18km/h) so it shouldn’t show -11m/s in any scenario. Can anybody please help me with this?

Thanks

The SRR demo was designed for AWR1642BOOST EVM. SInce the ODS EVM has different antenna, the angle information will not be correct.

So, using the AWR1642BOOST-ODS EVM will not provide correct results

Thank you

Hi Cesar

As you can see I don't have a problem with angle or range estimation. Problem is in the speed estimation section. is there any way to modify the project for AWR1642BOOST-ODS?

Thank you

No there is not. A BOOST EVM is needed

Thank you
