China's radars, located in Zhuangcheng and Ladakh, are intended to monitor and detect the Indian aerial activities. Chinese radars form a critical component of China’s national air defense capabilities.
The Chinese military developed several long-range air surveillance radars. This radar is capable of detecting up to 5,500km at a wide frequency range, ranging from 250 to 500MHz. This radar is part China’s latest generation network information system. It is designed to intercept incoming missiles as quickly and efficiently as possible. The radar is also designed for support of the missile-early warning satellite.
The Pband radar is used for detection of aircraft and missiles. It is capable of detecting targets from a distance of 5500 km. It is also very resistant to wind and anticlutter. The radar can be operated at speeds of up to 35 m/s. This radar has been exported to countries outside of its intended use. This radar was installed in China's navy formations. At least one system is reported to have been used to attack US Navy aircraft carriers.
YLC-8B is a mobile 3D surveillance radar that can be used at high altitude. The radar utilizes the latest digital technology for long-range detection and tracking of aircraft and missiles. The system was developed for PLA deployment and first presented at the China Air Show in Nov 2014. This radar uses two-dimensional active phased arrangement technology and mechanical scanning to detect multiple aircraft and missiles at once.
The L-band radar has a massive range of detection capabilities, allowing it to detect targets over 600 km. It is similar to the Thales TRS-2230 and ITT-Gilfillan 320. CRIA has included the radar in China's 2004 indigenous product listing. This radar is also used on the Luyang II-class of destroyers. The system includes adaptive MTI, CFAR and CFAR technology. This radar also uses civilian radio frequency-modulated signal, which can improve radar's viability.
China operates additional radars in addition to those mentioned above. These radars include ground wave radar (also known as over-the-horizon radar or OTH-B), Frescan systems, and backscatter systems. These radars can operate in different frequencies and each one can complement and help the other. China also operates various types of airborne radar early warning and control aircraft. These aircraft can extend China's radar coverage to other locations. In addition, some new generation Chinese SAM systems are capable of engaging stealth features, such as radars and other electronic counter-measures.
China has the P-band long range early warning phased radar. This radar is designed to intercept incoming strategic missiles, and is part of China's new generation of military network information systems. This radar is capable of intercepting strategic missiles within a short time period. It has a large detection range. China has been installing a surface search radar within the Sirjap area in recent years. This radar is located directly ahead of the PLA maritime station. China has also built infrastructure facility and watchtowers in Demchok.
