IWR1443BOOST: Long-range 3D performance

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR6843AOP, IWR6843, AWR1443, IWR1443, AWR1243, IWR1843BOOST

Hi,

 

I have been working with the IWR6843AOP for some time now for short-range applications (<20m). I am now looking for radar sensors to perform in more long-range applications, e.g. >40m. To this end I was looking for some feedback. The only requirements I have are that the sensor must be able to measure azimuth and elevation (so 3D returns), must be compatible with the OOB demo, and must be able to measure Doppler. As far as I am aware, the latter is always satisfied for the TI products in question.

 

 

As far as I am aware, longer range performance requires higher transmit power and larger max IF. If I'm not wrong (please correct me if I am), the transmit power on the mmWave evaluation modules is generally not changing, so really it's about max IF. For this I look at the following comparison tables from IWR6843

and AWR1443:

This would lead me to believe either the IWR1443 or AWR1243 to be the best fit. Of course, I would assume the antenna design has an impact on this performance as well. For example, this antenna comparison:

claims it should instead be IWR1843BOOST. Does it make sense then that our best bet is the IWR1843BOOST?

One point of confusion: I thought that the AWR and IWR lines of the same board were functionally quite similar, but there are quite large differences here between IWR1443 and AWR1443. Maybe I am missing something?
