AWR1443BOOST: Range Resolution Calculation

Yun Lou

Part Number: AWR1443BOOST

Hello,

The range resolution formula is given by rangeResolutionsInMeters = VelosityOfLight * ADCsamplingRate / (2 * freqSlope * NumberOfADCSamples) in capture.m. Can you explain how to derive this formula?

Thanks,

Yun

Hi Yun,

I've asked an IWR Team member to look at this and someone should have an answer for you tomorrow.

Cheers,

Yun,

You may refer mmWave training course page 12.

d_res = c / (2 * S * Tc)

The observation interval Tc = NumberOfADCSamples / ADCsamplingRate

Hi Yun,
You can find more details in the online training. Link: training.ti.com/intro-mmwave-sensing-fmcw-radars-module-1-range-estimation
If you have any further questions, please let me know. Thanks.
