AN/SPS-49

AN/SPS-49 - 2D long-range surveillance radar operating in the frequency band 300 - 1000 Mhz.


It is designed for use on board surface vessels. It has sufficient power to detect targets even at long ranges and is capable of effectively detecting low-flying targets. It is capable of automatic target detection, marking and assignment, and is equipped with anti-jamming protection systems that ensure good performance even under conditions of electronic interference, including meteorological effects and reflections from the sea surface and ground targets. The accuracy of the target coordinate measurement allows targets to be directly assigned to individual firing systems without the need for additional measurements.
The antenna is stabilised against vessel movement in the horizontal plane, and the radar uses digital data processing and transmission. It is capable of tracking 255 targets simultaneously.


The radar is available in several designs according to customer specifications.
AN/SPS-49(V)1 - basic version developed in the mid-1970s
AN/SPS-49(V)2 - version without electronic jamming protection system
AN/SPS-49(V)3 - modified version V(1) to work with Radar Video Processor (RVP)
AN-SPS-49(V)4 - modified version (V)2 for cooperation with the RVP system
AN/SPS-49(V)5 - modified version (V)1 equipped with Automatic Target Detection (ATD) and improved electronic jamming protection systems. Developed in the early 1980s. The radar is equipped with digital data output.
AN/SPS-49(V)6 - modification (V)3 with increased protection of individual systems and modified cooling system
AN/SPS-49(V)7 - modification of version (V)5 by systems of modification (V)6
AN/SPS-49(V)8 - modification of version (V)5 for use with AEGIS systems
AN/SPS-49A(V)1 - a modification released in the mid-1990s for use by the US Navy. Added systems to allow measurement of speed of all targets.
