MM/SPQ-5
MM/SPQ-5 “Sarchiapone” was an operating in the X-Band maritime surface surveillance radar, which was developed as an OTH experimental radar for the study of a wave propagation using ducting.
The antenna was a symmetrical parabolic antenna with a diameter of 3 meters with a hyperbolic Cassegrain auxiliary reflector. The parabolic reflector was much larger than necessary, resulting in extremely small side lobes. The transmitter and receiver were mounted directly on the antenna.
The MM/SPQ-5 was installed on the Italian frigate “Alpino” (F 580) from 1973 to 1987. It was able to locate aircraft during their take-off from the aircraft carrier „Kennedy“ at a distance of 350 nautical miles.
