The Type 518 radar is a Chinese high-performance
L band
The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower en ...
long-range shipboard
air surveillance radar. The Type 518 radar may be installed on destroyers or heavy tonnage naval vessels to detect long-range high-altitude aircraft in adverse natural noise and active
electronic jamming environments.
The Type 518 has been installed and deployed on the
Luhu-class destroyer and the
Type 052D destroyer
The Type 052D destroyer (NATO/OSD Luyang III-class destroyer) is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy. The Type 052D is a larger variant of the Type 052C; the Type 052D uses a canister-type, instea ...

sidelobe
In antenna engineering, sidelobes are the lobes (local maxima) of the far field radiation pattern of an antenna or other radiation source, that are not the ''main lobe''.
The radiation pattern of most antennas shows a pattern of "''lobes'' ...

cosecant squared antenna
A cosecant squared antenna, sometimes known as a constant height pattern, is a modified form of parabolic reflector used in some radar systems. It is shaped to send more radio energy in certain directions in order to smooth out the reception patte ...
