AN/SPS-55

The AN/SPS-55 is a navigation and surface search radar medium-range. It was developed by the U.S. company Raytheon, but is produced since 1971 Cardion Electronics (part of Ferranti Limited).

Description

The PLC 55 is primarily designed based on semiconductor technology, with the exception of the magnetron, which can simultaneously produce two different pulse lengths. The radar has several different modes of operation in order to remain operational even with interference from EloGm, clutter or interference. In addition to the usual linear polarization can be switched to a circular polarization to avoid clutter by heavy rain. Furthermore, can be detected and tracked even low-flying air targets. Due to its modern design, the SPS -55 is a very reliable radar. Statistically, it only comes every 1200 hours to a system failure, and this is usually caused by the antenna mechanics.
