Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Tool/software:

When using the AWR1843 and DCA1000 to collect data on high-speed vehicles (traveling above 60 km/h) in a road test, what would be the recommended range for the following configuration parameters in mmWave Studio?

Idle Time:
Ramp End Time:
Periodicity:
Number of Chirp Loops:

With the 3Tx4Rx configuration on the AWR1843,

Please give me some advice on these highlighted parameters in the context of my proposed detection scenario.(The mmWave radar is positioned for road testing, facing the side of vehicles traveling at speeds between 60 km/h -- 100 km/h.)

It would be great if you could explain the meaning behind the parameter settings!

Hello,

The AWR1843 is a reconfigurable device i.e by changing the parameters passed through the cli configuration you can change the range, range resolution, maximum velocity detectable and velocity resolution. For a sample starting configuration I recommend you look at the standard out of box profiles provided in the sdk

C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\demo\xwr18xx\mmw\profiles

A quick way to see what physical parameters these profiles map to is the mmwave sensing estimator. Please use the 2nd tab

If you would like to know more about what each parameter represents please go through the user guide and this paper
