OBORONA-14 SURVEILLANCE RADARS
Radar Modernisation Mission The Oborona-14 radar mo der nis atio n is carried out to replac e cathode-ra y vacuum tube components with solid-state devices and im pro ve radar tec hni cal and operational characteristics, including: • jam ming resistance to passive, as ync hronous pulse ja m m i n g and clutter from local objects; • data processing capacity; • data exchange within automated air defence syste ms, as well as fusing and identification of data received from several radars and other sources; • reliability and service life.
Composition The equipment intended for modernisation includes: • digital ECCM equipment for protection from passive and as ynchronous jam mi ng; • automatic radar data pick-up equipment and data collection set. The ECCM equipment based on detachable functional cells is integrated into a single line re pla c ea ble unit. It ensu res si mult a neou s electronic protection of the radar from passive and as ync hronous ja m ming in the coherent zone, and from as ync hronous jam ming in the amplitude zone, without loosing quality within the entire radar coverage zone.
Clutter suppression ratio, dB Passive interference suppression ratio, dB Simultaneous interference suppression ratio in coherent zone, dB, not less than:
The data pick-up equipment is mounted in the radar equipment van inste a d of the remotely-mounted plan positio n indic ator. M ou nti ng di m e nsio ns of the pick-u p equipment and PPI are the same. The data collection equipment is mounted on stationary command and control posts. Distance from the data collection equipment to the radar is not limited and depends on com mu nications channels available on site. Both data pick-up and collection equipment are computer-based.
