The JY-14 Radar System is a medium to long range air defense

Anti-aircraft warfare

NATO defines air defence as "all measures designed to nullify or reduce the effectiveness of hostile air action." They include ground and air based weapon systems, associated sensor systems, command and control arrangements and passive measures. It may be to protect naval, ground and air forces...

Radar

Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

Frequency modulation

In telecommunications and signal processing, frequency modulation conveys information over a carrier wave by varying its instantaneous frequency. This contrasts with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant...

 compression.This system can simultaneously track up to 100 targets and can feed the data to missile-interceptor batteries. It can track targets flying as high as 75000 feet (22,860 m) and 186 miles (299 km) in distance.

The system is notable for having wideband

Wideband

In communications, wideband is a relative term used to describe a wide range of frequencies in a spectrum. A system is typically described as wideband if the message bandwidth significantly exceeds the channel's coherence bandwidth....

 frequency diversity and adaptive pulse-to-pulse agility, enabling it to track even the most morphic radar signatures. It is the most common ground radar in China, and is rapidly being exported to other countries.

Manufacturer

The system is manufactured by the East China Research Institute of Electronic Engineering(ECRIEE), No.38 Research Institute (华东电工程研究所（中国电子科技集团公司第三十八研究所) in Chinese)).

The JY-14 system has been in production since 1998, and has since exported, most notably to Iran

Upgrades

The JY-14 can be upgraded to a more powerful power supply, giving it a wider range. This has been seen only in China so far, where multiple stations are tied together with the air defense system.
