J-20 development radar and avionics system

Test platform for J-20 development including radar and avionics system.

Test platform used to evaluate J-20's AESA radar.

A Russian Tu-204C was acquired and converted to act as an avionics flying lab for the J-20

 

JL3D-91B 3-D VHF radar possessing special anti-jamming, anti-ARM and anti-stealth ability

 

Translated script:
JL3D-91B is used to detect the position, distance and height of the 4th generation (FYI: China calls F22 alike as 4th generation; F16/F18 alike as 3rd generation) or conventional fighters. It owns good capabilities to detect stealth fighters and anti ARM missiles.

Second radar cross-section test range identified in China

Key Points

• Airbus Defence and Space imagery captured in 2016 shows a new radar cross-section test range in China
• A J-20 full-scale test article is present at the new test range, with apparent design changes suggesting either a new powerplant installation or a new aircraft variant under evaluation

IHS Jane's recently identified a radar cross-section (RCS) test complex in China. Airbus Defence and Space imagery captured on 24 April shows a recently completed test range northeast of Dingxin Airbase (AB) - the second new test site to be identified in the East Asian nation. The first one is located southwest of Beijing near Gaobeidian. A third possible site, predating the new complexes, is situated near Luoyang.

The location near Dingxin AB is well suited for a signature evaluation complex, with flat terrain and a lack of man-made or natural obstructions near the facility. Additionally, the configuration of the J-20 full-scale RCS test article present suggests design changes may be forthcoming to China's fifth-generation stealth fighter.

Along with the Gaobeidian RCS complex, the Dingxin RCS complex illustrates China's increasing attention to low-RCS aircraft design. The Dingxin RCS complex was constructed after the Gaobeidian site, which was built in the 2009 timeframe - perhaps in an effort to establish an RCS test range in a more secure location.
