OBSERVATION AND ANALYSIS OF 12GHz EELCTRIC-WAVE INTENSITY SCINTILLATION AT LOW ELEVATION ANGLE
12GHz电波的强度闪烁观测和结果分析

On the basis of authers developed data sampling and processing system, the 12GHz intensity scintillation of clear air turbulence has been observed and analysed at low elevation angle by tracing the sun. The experimental results are given and discussed. The con-clusions are obtained as follows: (1) Between 16° and 4°, the lower the elevation angle, the larger the sciatillation intensity in clear air will be. Scintillation is most probably to appear two or three days after rain. (2) The frequency at flection point (ft) appears, in general, between 0.1Hz and 1Hz.
