When a PLL is fixed on one of a large number of frequencies developed at a Doppler channel 'S', the frequency is selected and maintained in a range channel 'T2U2 . These frequencies generate radar echoes from a large number of targets, signal echoes returned through a number of paths ...
The Weather Channel and weather.com provide a national and local weather forecast for cities, as well as weather radar, report and hurricane coverage
A doppler control circuit for a CW or pulse Doppler Radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several targets and to further provide a phase lock loop which tunes the radar to a particular target ...

A direct-detection Doppler lidar system is demonstrated that uses a CCD as a detector for the first time to our knowledge. The ability to use this linear device with the circular output from a Fabry-Perot etalon comes from use of a circle-to-line converter [Appl. Opt. 29, 1482 (1990)...

Its essential feature is the so-called virtual motion, that provides Doppler shifts and temporal fading, but keeps all propagation parameters quasi-static and ensures Wide-Sense Stationary (WSS) for a small-scale movement of a mobile device. 2.2.2.2 Requirements for 5G channel models are still ...
