Part Number: IWR1642BOOST

Hi Champs,
Could you please let me know the range error if the absolute distance measurement is done by IWR?
The target range would be 0.3m, 1m, 3m, 10m, 30m, and 100m.
I would like to know the approx. range error for each distance measurement.

Best regards,
Hitoshi

Hello Sugawara San,
In the worst case the range error would be close to the range resolution. You could get an accuracy even better than the range resolution by using interpolation techniques etc.
The range resolution depends on the chirp configuration used. You can use the sensing estimator tool ( dev.ti.com/.../) to match the configuration to the max range you are looking for( 3 to 100m) , it would also indicate the corresponding range resolution for that configuration.

Regards,
Vivek

Hi Vivek,
Thanks.
mmWave Sensing estimator is very helpful for me to find possible configulation for requested range, etc.
