AN/APG-71

The AN/APG-71 is the digital upgrade of radar section of the AN/AWG-9, both used as nose radar in the fighter F-14 “Tomcat”. The radar incorporates a number of modes including velocity search (to provide maximum detection range capability against nose aspect targets), range-while-search (to detect all-aspect targets), and track-while-scan (which, when combined with an autonomous missile such as AIM-120, gives the aircraft a fire-and-forget capability).

The primary radar antenna is a mechanically scanning monopulse array, consisting of slots in a waveguide system. The visible dipoles in Figure 1 are part of the IFF interrogator.
