short-range surface-to-air missile. The system is installed on many modern, and retrofitted Chinese navy ships.
The Type 345 fire control radar appears to be based on the Thomson-CSF Castor CTM (Conduite de Tir Multisensor) fire control radar which is a Castor II/J with a separate IR camera (Piraña) and TV tracker and not the oft quoted Castor IIC. It is possible however, that the Castor IIC was bought initially but the CTM was also bought later.
It uses a TWT transmitter with a
Cassegrain antenna
In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspende ...
. Pulse compression (7.5 μs pulse) and pulse Doppler processing (first blind speed 1000 m/s) techniques are used and it can acquire ASHM at 18 km and fighter at 30 km with tracking range between 350 m and 30 km.
