Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642, AWR1243, AWR1443

Hi， I have encountered several problems when learning millimeter-wave radar. I hope to get some help.

Q1：The detection range of AWR1642,AWR1443,AWR1243，How to calculate it？

Q2:How does the maximum IF affect the performance of these modules？

Thank you!

Please see the mmwave training series

It explains the equations to determine the theoretical max range.

In practice, the max range depends on several factors: RCS of object detected, memory, Tx/Rx power ...

The AWR1443 can usually be used to detect cars up to 50-60 meters.

The AWR1642 can be used to detect cars up to 80-100 meters

The AWR1243 can be used to detect cars up to 150 meters

Thank you

Hi Cesar，Thank you for your answer.

Do you know which parameters of the MMW module are affected by the maximum if? Such as the measurementof range,velocity, direction.

Is the maximum IF the same as the IF bandwidth?

Yes,

For max IF you can use the value of IF provided in the datasheet.

The parameters affected by max IF are provided in the mmwave equations described in the training I mentioned

Thank you

Cesar
