For a long time, it was assumed that underwater communications were secure from eavesdropping. That assumption has now been shattered. Researchers from Princeton and MIT have developed a method to intercept underwater messages and locate…

Are you using radar chips for your small designs? Here's one for the books—and maybe some ideas for your designs, too. A research team at the University of Oxford wanted to help insect and bird populations that are at risk. They came up…

Using AI plus an open-source dataset could lead to rapid advancements in adaptive radar systems. Adaptive radar detects, locates, and tracks moving objects, rapidly taking pictures. With the help of modern AI approaches and lessons learned…

The Star Trek Universe has inspired many modern technologies, from transparent aluminum (aluminum oxynitride or ALON) to communicators (smartphones) to AI (Majel Barret is the best) and more. If you want a rundown, ask a Trekkie and brace…

We experience the Doppler effect constantly. Tracking the speed of cars with radar and locating satellites in the sky is all about how waves change frequency when a source, such as a radar signal and a detector, are in motion relative to…

Researchers at UC Davis developed a proof-of-concept sensor with the potential for millimeter-wave radars. They’ve dubbed the design a “mission impossible” made possible. These radars send fast-moving electromagnetic waves to targets to…

A new high-performance ‘phase shifter’ for advanced phase array antenna systems was developed at the University of Birmingham, using a liquid Gallium alloy, which varies the phase angle of microwave and millimeter-wave radio signals. The…

Piaggio Fast Forward rolled out a new technology for consumer and business robots and motorcycles and scooters. The technology includes 4D imaging radar provided by Vayyar expected to debut in 2022, while PFF robots will launch late this…

A Heriot-Watt University spin-out company is using smart technology to help safeguard Scotland’s roads and possibly bring an end to pot-holes. Gritting lorries dispersing salt along the roads are a familiar sight at this time of year but…
