IWR1843BOOST: Height (Y) Data Using MRR Demo

Part Number: IWR1843BOOST

Tool/software:

Hello,

We have successfully been using the 1843BOOST EVM to detect small drones out to several 10's of meters in an open air environment. We noticed the MRR visualizer includes the Y-Z chart (height vs range) only when the USRR clusters are active. Is it possible to utilize data from the MRR chirps/frames to specify the Y-component of the drone position? We would like to exclude the USRR frames as we are interested in detecting these drones at distances farther than 10-15 meters, which seems to be the detection limit for the USRR frames.

We are also potentially interested in switching to the MRR Beam Steering demo to potentially increase detection range. We do not need the full -60 to 60 degree Tx sweep, and would only utilize beamforming at -10, 0, and +10 degrees, though only 0 degree would probably be sufficient. Does the power of the Tx antennas combine for the MRR Beam Steering demo to possibly increase detection distance? The MRR (non-beam steering) user guide also states that all three Tx antennas are active for the MRR subframes. Is this accurate? The MRR beam steering demo user guide says the same thing and that USRR subframes are also active? Can you clarify how the MRR and MRR Beam Steering demos are different from the Tx perspective (i.e. Tx power combination, simultaneous active antennas, data processing, etc.), other than phase changes to steer the beam to wider angles?

Thank you very much for your help. I look forward to your reply.

Cheers,

Craig.
