AN/APG-73
The APG-73 is a late 1980s "upgrade of the APG-65 that provides higher throughputs, greater memory capacity, improved reliability, and easier maintenance". To reduce production costs, many of the upgraded radar's modules are common with the APG-70 (F-15) radar; its software engineers chose the JOVIAL programming language so that they could borrow and adapt existing software written for the APG-70. When fitted with a motion-sensing subsystem and stretch waveform generator and special test equipment, the APG-73 can generate high resolution ground maps and make use of 'advanced' image correlation algorithms to enhance weapon designation accuracy.
Since 1992 the APG-73 has been operational in U.S. Navy and Marine Corps F/A-18C and D aircraft; early models of the U.S. Navy F/A-18E/F Super Hornet; and in the air forces of Finland, Switzerland, Malaysia, Canada, and Australia. A total of 932 APG-73 systems were delivered, with the final delivery in 2006.
