Frequency diverse array (FDA) MIMO radar techniques represent a substantial evolution in radar system design, combining the benefits of frequency diversity with multiple-input multiple-output (MIMO) ...

More than 20,000 radio antennas will soon connect over the Internet to scan largely unexplored radio frequencies, hunting for the first stars and galaxies and potentially signals of extraterrestrial ...

A team of astronomers and engineers at ASTRON, the Netherlands Institute for Radio Astronomy, has successfully detected correlated interferometric radio signals, called “fringes,” from the sky with ...

As China's contribution to the world's largest intergovernmental international radio telescope project Square Kilometer Array Observatory (SKAO), the first batch of the China-built middle-frequency ...

Researchers have taken a step toward developing a type of antenna array that could coat an airplane's wings, function as a skin patch transmitting signals to medical implants, or cover a room as ...
