Interference-free GNSS signals are essential for more than just military vehicles and aircraft. Anti-jam systems usually suppress signals from interference sources by means of spatial filtering. These ...

A signal detected by a Chinese telescope and originally reported as possible evidence of extraterrestrial intelligence is almost certainly due to human factors, one of the researchers on the project ...

Reduced quality of reception is not your radio - it's a common atmospheric condition that causes interruptions for radio ...

A recent investigation led by Todd Humphreys from the University of Texas, Austin, found that the Russian Kosmos 2546 may have been used to jam GPS signals on a continen ...

Automotive radar systems have become a cornerstone of advanced driver-assistance and autonomous driving technologies, offering robust object detection and velocity estimation under diverse ...

Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

In the search for extraterrestrial intelligence, alien radio signals would be swamped by interference from radio sources on Earth. To confirm, researchers point away from the source and then back. If ...

Satellites depend on radio frequency spectrum to communicate with each other and with ground stations on Earth, but spectrum is a finite resource that’s prone to interference — an issue that’s only ...

As electronic devices saturate all corners of public and personal life, engineers are scrambling to find lightweight, mechanically stable, flexible, and easily manufactured materials that can shield ...
