AN / SPS-67
The AN / SPS-67 is a medium-range ship-based surface search radar . It was initially manufactured by Norden Systems until Northrop Grumman took over production.
development
The SPS-67 was developed to replace the now outdated AN / SPS-10 . The advantages of the new radar include improved ECCM capacities, low- flying detection and greater reliability. These differences essentially result from the fact that the SPS-67 uses modern digital components in contrast to the analog assemblies of the SPS-10, although it should be noted that its grid antenna was also used with the SPS-67. The system was introduced to the US Navy in 1977 and has since been replaced by the C-band Active Array Radar ( CBAAR ).
description
The SPS-67 is primarily designed for navigation and the detection of surface targets, but it can also detect low-level targets such as anti-ship missiles and aircraft. In order to meet these diverse requirements, the radar has a large number of operating modes. Furthermore, emphasis was placed on reliable electronics, so that mainly digital components were used, which are easy to exchange and have a self-diagnosis function. In order to suppress the clutter and interference caused by waves , additional computer systems have been developed which are specialized for this task. The radar also has an integrated IFF transmitter.
variants
- AN / SPS-67 (V) 1: The basic version.
- AN / SPS-67 (V) 2: This variant is identical to the previous one, but the antenna has been replaced by a more modern and compact model.
- AN / SPS-67 (V) 3: This new version has been available since 2000. The radar now has a digital MTI mode as well as improved clutter suppression and automatic target acquisition and tracking. In addition, the system can now pass on target data to the Aegis combat system , with more than 128 targets can be tracked.
