Radar Reflections from a Clear Sky in the 35 GHz Range

The operating experience of a wind profiler operating at a frequency of 35 GHz is considered. Particular attention is paid to radar reflections from the clear sky (angels), which can be detected down to a level of –60 dB Z . We showed that, in some cases, clear-sky signals cannot be interpreted with...

description The operating experience of a wind profiler operating at a frequency of 35 GHz is considered. Particular attention is paid to radar reflections from the clear sky (angels), which can be detected down to a level of –60 dB Z . We showed that, in some cases, clear-sky signals cannot be interpreted within the framework of the traditional theory of reflections from turbulent irregularities. The impossibility of interpreting the received signals as reflections from insects or large aerosols is statistically substantiated. Various putative sources of clear-sky reflections in a given wavelength range are considered.
