Emerson Electric Company's AN/APG-69 is an X band coherent pulse doppler radar originally designed for the F-20 Tigershark aircraft. It is the successor to the AN/APQ-159. Northrop Corporation skipped over the APG-69 for the F-20, choosing the General Electric AN/APG-67 instead. The APG-69 was still used by other Northrop F-5 operators, and other light fighter projects, including the Swiss Air Force ALR Piranha aircraft.
