JY-14 Radar

The JY-14 Radar System is a medium to long range air defense radar produced and used by the Chinese. It is capable of detecting multiple targets within its range and determine their parameters, tracking them even through surface clutter and ECM jamming. It utilizes a frequency-agile mode with 31 different frequencies, has a large band of ECCM operating parameter frequencies, and uses linear FM 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 convert|75000|ft|m|-2 and convert|186|mi|km|0 in distance.

The system is notable for having wideband 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.36 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, Vietnam, and Venezula. [L.

Xu, "The Challenges and the Ways to Deal With--Where is Airborne Fire Control Radar Going," Proceedings of the National Aerospace and Electronics Conference, NAECON 1993, 1, 303-309.]

Notable Incidents

According to US intelligence, Iran has been purchasing the JY-14 radar system since the late 1990s, but China reportedly has accelerated the project since the start of U.S. military operations in Afghanistan. [China steps up air-defense work on Iran's border fears," Washington Times, 18 October 2001, p. A3.]

Additionally, several JY-14 radars have been found operating in North Korea, according to US intelligence sources, along the DMZ. "Chinese Radar Operating in North Korea may indicate closer military ties," Sectorwatch, 4 July 2006, p.32]

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.
