This reflected signal is then received by the radar during its listening period. Computers analyze the strength of the returned radar waves, time it took to travel to the object and back ...

Radar worked by sending out a radio wave and analyzing the reflected wave after it bounced off any objects in the air. The rectifier's job was to translate the reflected signal into the direct ...

His design also includes frequency modulation, which means that it will be able to determine an object’s distance as well as its speed. There are many other design considerations for a radar ...

has developed a new radar signal–processing technology that can dramatically enhance the resolution of existing low-resolution radars. This technology enables precise object recognition using ...

The Doppler principle was discovered in 1842 by an Austrian physicist named Christian Johann Doppler and has been used to measure speed since 1948. The police radar transmits a signal at the target at ...

Researchers have developed a new radar signal–processing technology that can dramatically enhance the resolution of existing low-resolution radars. This technology enables precise object ...

SETI scientists suggest that extraterrestrial civilizations could detect Earth through 'technosignatures' like planetary ...
