MGR

The MGR (Turkish: Milli Gözetim Radarı, or national surveillance radar) is an S-band 2D pulse-Doppler radar designed for air traffic control. Operating at an average pulse repetition frequency of 830 Hz and a peak power of 15 kW, it offers an instrumented range of 60 nautical miles (110 km) with a range resolution of less than 200 meters. This fully coherent radar features frequency diversity and includes a dedicated weather channel capable of detecting six levels of reflectivity. Its antenna, a replica of the G-33 primary radar and ALE-9 MSSR antenna from Leonardo's ATCR-33S, utilizes a parabolic reflector to generate a cosecant-squared pattern, with two feed horns for high and low beam patterns. The antenna has a beamwidth of 2° and rotates at 12 revolutions per minute, with switchable linear and circular polarization. A prototype of the MGR is installed under a protective radome at Gaziantep Airport, Turkey (36°56’29.24" N 37°27’42.36" E), and underwent its initial flight inspection for certification on February 24, 2020.
