Secondary surveillance radar for RSP-10M system

This paper explains the upgrading of the Russian RSP-10 radar system, which is still employed by several customers. The main topic is the incorporation of the ICAO secondary radar system into the system combining the primary surveillance radar antenna at L band, ICAO and Russian UVD standard. The design uses a phased antenna array that make up the SUM and DIF antenna pattern. These patterns are shaped by common reflector antenna. The correct separation of the side lobes between the SUM and DIF beams in the ICAO band will ensure the OMNI antenna. The UVD standard uses an antenna array with three dipole elements that works as receiving part of the UVD.
