In order to fight rebel use of small,
single engine civilian aircraft as light bombers, Sri Lanka is buying, for $5
million, a Chinese JY11 low altitude radar. This system has a max range of 180
kilometers, and can spot aircraft flying at tree top level, up to nearly 50,000
feet. The 3-D radar is mobile, requiring three large trucks to transport it
all. The JY11 can also deceive many radar detectors.
