AWR1843BOOST: What is the phase of the chirps transmitted between antennas in the MRR profile of the MRR lab?

Hi, I know that in MRR profile the radar transmits with the 3 TX antennas at same time, but what is the phase between the chirps transmitted by antenna 1, 2 and 3?, it is 0 degrees or 180?, the documentation does not specify this

Thanks

Hi,

The phase in the MRR demo is 0deg.

Notice that there is another demo based on the MRR demo where we added beamsteering.

labs\lab0011_mrr_beamsteering

In this demo the hardware phase shifter available on AWR1843 is used to apply different phase shifting so that the overall beam is steered at a certain angle.

thank you

is there any function/doc that specifies that?, I would like to transmitt with the three antennas in phase

The default configuration is 0deg phase shift.

The 3 Tx should be in phase

thank you
