Abstract:

The report considers the possibilities of a radar operating with various sounding pulse lengths for the study of dynamic processes in the atmosphere. It is most expedient to use a radar emitting sounding pulses of different length alternately during a period of frequency iteration. The use of a two-channel selector with frequency selection at each F brep2 permits the obtaining of radar signal envelopes and their spectra simultaneously for two pulse lengths. Then changes in the turbulence mode, scatterer-size spectra and mean wind speed will not affect the measurements of Epsilon. This technique will probably allow measurement of the temporal variations of Epsilon. Author
