Good video. So if I understand this correctly, when a radar is transmitting in CW and tracking a target, RGPO is useless. Likewise when a radar is not transmitting in CW and tracking a target. VGPO is useless. Does this sound right?
Do you have more videos on EA techniques?

Band 28 is an FDD band in the 700 MHz range. I am not a smartphone expert and cannot state which phone supports rank 4 in the lower bands, but in general 4x4 MIMO is supported in the mid and high bands in smartphones (low bands antennas have a bigger size). From deployment perspective 4x4 MIMO is used in cities where high capacity is needed (in mid to high bands because of the higher available bandwidth) and where more multipath is available.

Can RGPO used to break missile lock on or only the VGPO

Both. In some applications, RGPO and VPGO are used simultaneously
The missile does not, in fact, know where it is

In absolute terms, yes, but it does usually know where it is relative to the target :)
