other names = unknownThe JY-9 Radar is a mobile
S-band low altitude searchradar intended for use in air defense, gap filling, airport surveillance and coastal defense. It is designed for effective detection of targets at low altitude in both ECM and naturalclutter environments.ystem construction
It consist of a radar/operations shelter, an antenna pallet and a power station shelter and is transportable by air, rail, and sea. It has a setup and dismantle time of 90 minutes by a team of 8 men.
The JY-9 employs a dual-beam antenna assembly consisting of a deformed
parabolic reflector , two horns and two feed channels. One channel is used for transmit, but both are used for receive. The antenna rotates at 6 or 12rpm to provide all round coverage and can be mounted on a shelter or on the ground.The JY-9 has high anti-jamming and anti-clutter capability due to the use of advanced techniques, including pulse to pulse frequency agility, dual channel, JATS, wide operating band, low sidelobes,
MTD automatic spectrum processing, automatic clutter map and automatic residue map. The mean time between failures is better than 900 hours with Built-in test equipment (BITE).The system is manufactured by the East China Research Institute of Electronic Engineering(ECRIEE)/No.38 Research Institute.
