The avionics suite of the F-14D is centered around the Hughes AN/APG-71 radar. The APG-71 is a development of the APG-70 used in the F-15E Strike Eagle. It features a digital processor, a low-sidelobe antenna, a sidelobe-blanking guard channel, and monopulse angle tracking, all of which are intended to make the radar less vulnerable to jamming. It features a low-sidelobe antenna, a sidelobe-blanking guard channel, and monopulse angle tracking, all of which are intended to make the radar less vulnerable to jamming. It has a power output of 5 kilowatts ads compared to 2.8 kilowatts for the F/A-18, which endows it with superior long-range radar capability. It has both low and high-pulse repetition frequencies. The low PRF mode is used for single-target tracking and for ground mapping, whereas the high PRF is used for long range search. The AN/APG-71 can track more than 24 targets simultaneously, and has an acquisition range of up to 400 nautical miles. By using a fighter-to-fighter link, the radar from one aircraft can hand-off to the radar of another fighter, giving it "eyes" to the full range of the system. The F-14D is compatible with the Joint Tactical Information Distribution System (JTIDS), which integrates communication, navigation, and identification codes into a single jam-free system for multi-service use."
