The National Surveillance Radar (MGR) System, designed and produced within our Institute, was later made redundant for RF units. Within the scope of the project, RF Front Receiver Drawer, RF Transceiver Drawer and spare units of the microwave distribution network were integrated into the system. In the redundant radar system, in case of any malfunction in the existing channel, operation can be continued by switching to the backup channel and necessary repairs and replacements can be made in the main channel. As long as there are no malfunctions in both channels at the same time, malfunctions that may occur in the radar system do not interrupt the operation of the system. The first redundant MGR System was implemented at Oğuzeli (Gaziantep) Airport.
