mmWave - Two sensor modules on the same board

I’m using the mmWave Human Detection Sensor Kit in a project for monitoring of elderly people. It works really well with the MR60BHA1 60GHz module, however, I would like to add fall detection as well, for which I could use the MR60FDA1 module.

Would it be feasible to combine these two modules on one board? The distance between the two modules would probably be less than 1 cm, and I fear this might influence the performance or accuracy of the mmWave radars on the two modules.

Yes, you cannot combine two radars together as it will cause mutual interference between them.
