MM/SPQ-2
MM/SPQ-2 is a surface search and navigation radar operating in the X-Band, with which even low-flying aircraft could be located.
The very good directivity of the antenna was provided by a 3 m wide parabolic reflector. Alternatively, a waveguide slot antenna could be used and the radar was then called SPQ-2B.
The radar has been fitted to numerous Italian Navy ships since 1970, including the frigate Alpino and the cruiser Andrea Doria. Modernized versions SPQ-2D were exported to Canada in the mid-1980s. The Italian radars were decommissioned around 2006.
