Could This Radar Spot Malaysia's Missing Plane?

As the search for the missing Malaysia Airlines flight intensifies, a new advanced radar system has been unveiled by scientists. But could it spot the plane?

The world's first photonic radar was tested at Pisa Airport in Italy and achieved "world-class" performance, according to an independent expert.

It uses lasers to produce high fidelity signals that pinpoint planes precisely.

But there are doubts over its range, say researchers in Nature journal.
