I have seen some of the equipment used by FCC field agents when DFing deliberate interference to aircraft communications. They used three transportable fixed mountaintop installations ringing the area of interest that measured field strength and also recorded transmitter spectra for later identification of the suspect transmitter, and three mobile equipment sets employing directional antennas used in a small-city urban area.
