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 ...

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 ...

Today, at the 2015 International Solid State Circuits Conference (ISSCC), imec and Panasonic presented a transceiver chip for phase-modulated continuous-wave radar at 79GHz. This achievement ...

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 ...

Pulse compression is an important technology in modern radar systems and promotes the developments of modern radar technologies towards higher speed and ranging accuracy. The frequency-modulated ...

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 ...

Human activity recognition (HAR) using frequency-modulated continuous wave (FMCW) millimeter-wave radar is a promising alternative to wearable and vision-based systems due to its unobtrusive and ...

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 ...
