The observation of direct solar radiation in urban district of Beijing was carried out with a PIS spectrometer from March 1993 to March 1995.

利用ＰＩＳ太阳光谱仪观测了北京地区１９９３年３月—１９９５年３月晴天和少云天气的太阳直接辐射光谱，波长范围为０。

A method of determining atmospheric optical depth spectra from wide-band direct solar radiation is presented.

利用１９６６年和１９６８年珠穆朗玛峰地区科学考察期间得到的太阳直接辐射光谱资料，获得了该地区大气气溶胶光学厚度谱。

By using the data of global radiation,direct radiation and scatter radiation from 112 stations,and cloud cover from 729 stations in China during 1961 to 2000, the inter-decadal anomaly spatial distribution and change were analyzed.

利用中国122个辐射观测站1961—2000年的逐日地面辐射资料,同期729个气象站的逐日云量资料,分析了总辐射、直接辐射和散射辐射年代际距平分布和变化。

By usingreal-time solar radiation and scattered radiation data at the four stations of Beijing,Guangzhou, Shenyang and Wuhan from 1961 to 2003, statistical analyses show thatthe total solar radiation and direct radiation gradually decrease in recent 43 years,and both have positive departure before 1980s by contrast to negative departure after1980s.

对43年的资料进行统计分析，结果表明：近43年来，四个站的总辐射和直接辐射呈逐渐减少的趋势，在80年代以前为正距平，80年代以后为负距平，而散射辐射减少不显著，广州、沈阳甚至有增加的趋势，说明太阳总辐射的下降主要是由直接辐射的变化引起的。

By using the data of global radiation,direct radiation scatter radiation for 112 station,and cloud cover for 729 station in China during 1961 to 2000,Inter decadal anomaly spatial distribution and change of global radiation,direct radiation and scatter radiation in China were analyzed.

利用中国122个辐射观测站1961～2000年的地面辐射资料,同期729个气象站的云量资料,分析了中国总辐射、直接辐射、散射辐射和云量的多年平均分布,总辐射、直接辐射和散射辐射年代际距平分布和变化。

Regular radiometric calibration techniques developed for high frequency narrow band radar system are not applicable for low frequency ultra-wideband radar (UWBR).

针对高频窄带系统的常规雷达辐射校准技术不能适用于低频超宽带雷达系统。

The changes of the RCS of the calibrator with the incident angle of electromagnetic wave cannot be neglected during the radiometric calibration.

低频SAR天线通常具有极宽的方位向波束角 ,在辐射定标时 ,定标体RCS随雷达波入射角的变化不能够忽略 ,文中利用低频散射模型 ,得到定标体RCS随角度变化关系 ,结合条带式低频SAR的工作原理 ,给出辐射校准的方法 ,并进行仿真试验 ,验证了该方法的有效
