AWR1443BOOST: Speed of vehicle

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1443

Hello,

Can we use AWR1443BOOST, to measure true ground speed of vehicle like the conventional CW Doppler radar which is generally mounted on vehicle at 55 degrees ? If yes at what angel we should mount the same on vehicle?  Then how to use this angle information to calculate speed?

Any example if exist please share the same. 

Thanks & Regards

    Hi Prashant,

    There is no specific example or experiment available to this use-case. Although in this case you need to rely on road clutter to find the vehicle speed.

    The angle of sensor placement needs to be found based on different experiments.

    Hello Jitendra,

    Can we measure speed of vehicle using AWR1443BOOST?   What do you mean by rely on road clutter to find the vehicle speed,Can you elaborate ?

    Hello Prashant,

    As I mentioned earlier that we don't have full proof experiment of this usecase but it is possible to measure vehicle speed using mmWave Sensor. Based on memory requirement I can't confirm with AWR1443 but based on the experiment it may possible.

    To measure the speed, it would require to measure the speed of clutter/reflection from the road when EVM is mounted on the vehicle at some angle.
