This paper presents two methods for cloud detection : multi - channel dynamical threshold algorithm and apparent reflectance algorithm
本文介紹了兩種雲檢測演算法：雙通道動態閾值法和表觀反射率法。 -
The apparent reflectance algorithm estimates the clear - sky visible apparent reflectance as the bases of visible channel thresholds with the 6s radiation transfer model. cloud detection is tested with apparent reflectance algorithm to gms5 images
將表觀反射率乘以不同的系數得閾值，待檢測雲圖的表觀反射率大於閾值的像元為雲像元。 -
This paper comprises two parts : radar clutter simulation and adaptive moving target indication. in the former part, we analyse the generation mechanism of single - channel radar correlated clutter and illuminate the simulated modeling way of rayleigh, log - norm, wei bull, k - distributed clutter with special power spetrum. all these models are used into the practical simulation of ground clutter, cloud - rain clutter and chaff jammer according to their features
在雷達雜波模擬部分分析雜波的產生尤其是單通道相關雷達雜波產生的機理，具體闡明了在指定雜波功率譜情況下，幅度服從瑞利分佈、對數正態分佈、韋伯分佈和k -分佈的雜波的建模與模擬方法，並根據不同分佈的特點，將其應用到地雜波、氣象雜波和箔條干擾的模擬中。 -
Through the analysis of 11 typical mesoscale convective systems occurring at china continent and adjacent ocean on june, july and august, 1998, it is found that 10. 65ghz v channel and 19. 35ghz v channel can well response to the absorbability and emission of liquid water in cloud and precipitation, and that 85. 5ghz v channel and 37. 00ghz v channel can response to the ice scatting in cloud well
通過對1998年68三個月內發生在我國大陸和鄰近洋麵上的11個中尺度對流系統的分析，發現10 . 65和19 . 35ghz垂直通道能較好的反應雲中液態水和降水的吸收和發射85 . 5和37 . 0ghz垂直通道能較好的反應雲中冰晶冰粒的散射。 -
First, under the given boundary condition and reasonable simplified condition, this paper develops radiation transmitting equations in atmosphere applied in infrared waveband and visual light waveband from common equation of radiation transmitting. then, the formula between observation of satellite and net surface radiation is established according to the developed equations, from which it is found that net surface radiation is relative to sun zenith, land surface and cloud albedo, etc. at last, by using data of satellite visual light ( vis ), infrared 1 ( ir1 ), infrared 2 ( ir2 ) and water vapor ( ir3 ) channel, sun zenith and net surface radiation, a regression formula is built
本文從大氣中太陽輻射傳輸的一般性方程入手，引入邊界條件及簡化條件，推導出紅外波段和可見光波段的大氣輻射傳輸方程，由此建立起衛星觀測輻射與地面凈輻射的關系，文章還就衛星觀測到的輻射與雲量、雲高、雲的光學厚度、雲及地面反照率等之間的關系進行了理論分析，可以幫助更好地理解雲對地面凈輻射的影響。
