The radar system that Taiwan says tracked the PLA’s ballistic missile launch
The Pave Paws early-warning unit detected the launch from waters near the mainland’s southern coast, report says

The system tracked the missile’s trajectory during the initial phase of flight while it remained within the radar’s coverage, the official said.
The giant radar is housed at the Leshan Radar Station in northern Taiwan’s Hsinchu county and was bought from the United States.
At 2,600 metres above sea level, it can detect missile launches up to 5,000km (3,100 miles) away, making it a cornerstone of Taiwan’s early-warning network.
The radar’s range allows it to monitor a wide area covering mainland China, the South China Sea and the Korean peninsula. Taiwan’s customised version of the system has also been upgraded to improve detection of low-altitude cruise missiles and tactical ballistic missiles.
