HARM = High Speed Anti-Radiation Missile
The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2. HARM, a U.S. Navy-led program, was initially integrated onto the A-6E, A-7 and F/A-18 and later onto the EA-6B. RDT&E for use on the F-14 was begun, but not completed. The USAF introduced HARM on the F-4G Wild Weasel and later on specialized F-16s equipped with the HARM Targeting System (HTS). The HTS pod, used by the USAF only, allows F-16 to detect and automatically target radars with HARMs instead of relying on the missile sensor alone.

Yea, that’s the HARM I like best for this. I saw several other definitions of what HARM meant but I do like this one best. :)
