VIRTUAL ANTENNA ARRAY VERTICAL SOUNDING RADAR CONCEPT FOR SOLVING SUPER-RESOLUTION PROBLEMS

Crede experto
Due to the significant increase in the density of traffic flows, especially air ones, technologies of high-precision spatial determination of air objects are increasingly being introduced into ground-based radio engineering transport control systems. The

Experimenting With Frequency‐And‐Angular Sounding to Characterize Traveling Ionospheric Disturbances Using the LWA‐SV Radio Telescope and A DPS4D

Radio Science, 2019
Here we present near vertical angle of arrival and Doppler observations using a Digisonde Portable Sounder 4D (DPS4D) as a transmitter and the Long Wavelength Array at Sevilleta (LWA‐SV) radio telescope as a receiver, over an 80‐km baseline.

Analysis of sounding signals of radioacoustic sounding systems of the atmosphere in the functional space

Radiotekhnika
Systems of radio acoustic sounding (RAS) of the atmosphere provide information on the state of processes occurring in the lower layers of the atmosphere. They allow measuring vertical profiles of atmospheric temperature, wind speed, and air humidity. The
