Passive radar systems harness pre-existing electromagnetic emissions to detect and track objects without the need for dedicated transmitters. By exploiting so-called illuminators of opportunity such ...

In winter, avalanches pose the biggest danger in the mountains. Avalanche monitoring is therefore of critical importance to ensure the safety of people and infrastructure. Researchers at the ...

It is an old trope in submarine movies. A sonar operator strains to hear things in the ocean but dares not “ping” for fear of giving away the boat’s location. Radar has a similar problem. If you want ...

The basic principle of radar systems is simple enough: send a radio signal out, and measure the time it takes for a reflection to return. Given the abundant sources of RF signals – television signals, ...

Israel Aerospace Industries’ Elta Systems subsidiary on 27 October unveiled a new Passive Coherent Location (PCL) system that creates an air situation picture using non-emitting target detection.

A programmable metasurface stamps temporal codes onto ambient radio waves, enabling passive radar to detect and track drones with active radar precision and zero dedicated transmission. (Nanowerk ...
