Motion detectors use Infrared, Microwave or ultrasonic

RF is for RADIO FREQUENCIES so if it is going off then you have a radio
transmitter somewhere nearby.  Sounds like you have a very low power
transmitter (often found in high-tech covert surveillance equipment)
that is very hard to detect.  Sometimes, however, the human body can act
almost like an antenna (ever had your radio station go in and out based
upon where you were standing in the room?) and you lucked upon the
perfect position from which to detect your transmitter.

Maybe you can use that to help narrow down where it is...
