What you’re describing is called notching or hiding in the ground return/clutter that the radar sees by flying low to the ground and perpendicular to the aircraft you’re trying to hide from so the effective closure rate is the same as the offensive aircraft’s speed since modern radars use Doppler shift to locate targets. This strategy will not work on flying objects that are high enough to not be hidden in the ground clutter and especially if the defensive aircraft is higher than the emitter since it will be giving off a pretty strong return.
However other parts on aircraft give a huge return. Compressor blades from a jet engine or blades from a helicopter or drone would also show up like a flashlight in the dark.
