Large Phased Array Radar (LPAR)

Large Phased Array Radar Latest News

China recently deployed a powerful Large Phased Array Radar (LPAR) in Yunnan province, near the China-Myanmar border.

About Large Phased Array Radar

• It was established by China in Yunnan province, near the China-Myanmar border.
• It boasts a surveillance range exceeding 5,000 kilometers, allowing China to monitor extensive areas of the Indian Ocean and deep into Indian territory.
• It possesses the capability to detect and track ballistic missile launches in real time.
• Unlike traditional radars, which rely on mechanical rotation, LPARs use electronically controlled antennas to scan vast areas almost instantly. 
  • This allows them to track multiple targets, including ballistic missiles, with high precision. 
  • Such radars play a critical role in early warning systems and air defence networks.

How does China's Large Phased Array Radar (LPAR) Compare to the World?

• Besides China, only the US and Russia have the LPAR system. 
• The capabilities of China's LPAR are being compared to the US PAVE PAWS (Precision Acquisition Vehicle Entry Phased Array Warning System), a Cold War-era radar designed to detect long-range missile launches. 
• The American system has a detection range of approximately 5,600 km and can track multiple projectiles, including submarine-launched ballistic missiles.

Concerns for India

• The Yunnan-based LPAR can monitor deep into Indian territory and track missile tests conducted from Dr APJ Abdul Kalam Island off India's eastern coast. 
• This site is crucial for testing strategic weapons like the Agni-V intercontinental ballistic missile and the K-4 submarine-launched missile.
• By capturing vital data on missile trajectories, speeds, and distances, China gains a strategic advantage, enabling it to analyse and develop countermeasures.
