There aren’t many Hackaday Prize entries playing around in RF, save for the handful of projects using off the shelf radio modules. That’s a little surprising to us, considering radio is one of the ...

For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the nonlinear junction ...

Recovering speech in the absence of the acoustic speech signal itself, i.e., silent speech, holds great potential for restoring or enhancing oral communication in those who lost it. Radar is a ...

The smaller and lighter electronics get, the more ways they can be used. A team of researchers has come up with a compact radar system the size of a matchbox that could be deployed in drones, guidance ...

Imec, in collaboration with Vrije Universiteit Brussel, Brussels, Belgium, presents the world's first 79 GHz radar transmitter implemented in plain digital 28nm CMOS. With an output power above 10dBm, ...

Millimetre-wave radar systems operate in the 30–300 GHz band, exploiting short wavelengths to attain high spatial resolution and compact form factors. Recent advances in semiconductor processes, ...

Transportation systems are critical to moving individuals and freight quickly, efficiently, and safely around the world. So transportation systems and the associated infrastructure must respond to ...

Detects vehicle speeds from more than 180 meters away and sends speed data to traffic systems for road monitoring, and ...

The radar measurement method plays a progressively important role in the wastewater and water field. This is specifically revealed by the "Metering outside of the medium" trend. Flow measurement by ...

A new advance in health monitoring which uses radar to "listen" to patients' heart sounds with remarkable accuracy could lead to a new generation of contactless medical monitoring equipment.

Radar (acronym for Radio Detection and Ranging) uses radio waves to detect objects in the environment. It allows determining the distance (known as range), angular position (bearing), and velocity.

In the previous entries of this blog dedicated to automotive radar, the reason for using radar and the principle of operation of the frequency modulated continuous wave radar were presented. Now, we ...
