РАДИОЛОКАЦИОННЫЕ ОТРАЖЕНИЯ ОТ ЯСНОГО НЕБА В МИЛЛИМЕТРОВОМ ДИАПАЗОНЕ ДЛИН ВОЛН

Abstract

The fine structure and conditions for the occurrence of radar reflections from a cloudless atmosphere in various meteorological conditions and at different times of the year are considered. The few research results in the millimeter wavelength range determine the importance and relevance of the tasks in this area. The results of field measurements carried out using a radarof 8 mm wavelength range at different times of the year under various weather conditions are presented. The possibilities of the developed software for processing and analyzing the data are considered. The obtained data can be used in the design of all-weather small-sized weather radars for various purposes. The parameters of pulse Doppler radars of 8 mm wavelength range for measuring wind profiles in a wide range of weather conditions are presented. Sensing modes, methods for processing and accumulating data using software, as well as the form for presenting the results are indicated. The technique of wind profile recovery in the directions of sounding is considered. The data on radar reflectivity in a clear sky in various meteorological situations are given. Separately, the features of the structure of the Doppler spectra in the millimeter wavelength range when reflected from the clear sky are considered.
