Lightweight contender

摘要

A shoebox-sized synthetic aperture radar (SAR) a hundred times lighter than standard equipment has been successfully tested on Boeing's ScanEagle unmanned aircraft. Manufacturer ImSar claims its NanoSAR, which can see in hazy, cloudy, rainy or foggy conditions, is the world's smallest. It weighs just 900g, compared with existing devices of between 23kg and 90kg.
