Understanding RGPO and VGPO

This video provides a brief technical introduction to range gate pull-off (RGPO) and velocity gate pull-off (VGPO) and how they are used in deceptive radar jamming.

Thank you. I've been looking for someone who provides info that's more in-depth than just explaining doppler. Great channel! Wouldn it be possible to use pulsed pattern variations (like a song almost) to make spoofing the source more challenging ..?

[@poojasrivastava5260]

Very well explained.. good effort

Thanks!

Great video

Thank you!

Good vid and useful info

[@pauldenisowski]

Thank you!

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?

[@fluffygamer6394]

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

[@pauldenisowski]

Both. In some applications, RGPO and VPGO are used simultaneously

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.

The missile does not, in fact, know where it is

[@pauldenisowski]

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