A lecturer at MIT taught his students how to build their own Synthetic Aperture Radar (SAR) for one of their projects at the institute this semester. The SAR is a high-resolution radar that is usually used in moving vehicles like airplanes and used for ground mapping purposes. What’s so special about the radars the students were making is that all they used were some breadbordable electronics, empty coffee cans and a laptop. Talk about playing MacGuyver! The details and instructions of how to make the SAR aren’t released yet, but the lecturer has promised to release them once the class is finished. Head over to the students’ website for more details.
