"Beam Manuever"

I have looked and read at a lot about aircombat, I knew there were
tactics to help defeat a radar advantage one plane had over another.
Shortly after the Persian Gulf War I found out about the “beam
manuever”. I have not found much else about this or other tactics
design to nullify the advantage of airborne radar.
I read that the beam manuever works because it fools the software that
supposed to eliminate ground or sea clutter. “If you are flying a F-14D
or F-15C and you are lower in altitude than the target aircraft, will
the beam manuever work or fail, since then is no need for filtration of
ground or sea clutter?”
