Tiny, fast, accurate technology on the radar

Phys.org  April 8, 2019
An international team of researchers (Italy, Saudi Arabia) has developed a low-power, portable frequency-modulated continuous wave (FMCW) radar with an operating frequency of 24 Gigahertz. It has one transmitting and two receiving antennae, meaning it can better estimate the angular location of a target. The device fits into a 10-centimeter box, weighs less than 150 grams and is powered by a 5V battery. Initial trials suggest the device is capable of target detection, speed estimation and tracking at ranges of up to 12 meters. Possible applications include object detection for visually impaired people or unmanned moving devices and healthcare and personal security…read more. TECHNICAL ARTICLE
