摘　　要：气象辐射计量检测用太阳模拟器是对气象辐射观测仪表-太阳总辐射表进行质量考核的一个重要检测设备,其性能直接影响总辐射表的考核质量。在对太阳模拟器的结构组成和工作原理的论述基础上,重点了研究了太阳模拟器的光谱匹配度、辐照强度及调节范围、辐照不稳定度、辐照不均匀度和光束准直性等性能指标的测试方法,并根据大量的试验数据对其性能进行了分析。采用滤光片对氙灯光谱进行修正,采用光学衰减片来提高低辐照度的稳定性,通过氙灯和光学积分器投影镜离焦的方式提高辐照不均匀度。结果表明研制的气象检测用太阳模拟器的光谱相匹配度达到AM1.5中A级标准,辐照强度在100～1250W∕m2连续可调,辐照不稳定度达到±1%,辐照不均匀度在Φ100mm和Φ200mm范围内分别达到±1%和±2%,满足气象辐射计量仪表检测的需要。Meteorological radiation measuring solar simulator is an important testing equipment used to detect the quality of the total solar radiation meter. Its performance has a direct impact on the quality of total radiation table. On the ba- sis of the structure composition and working principle of the sun simulator, the spectral matching, radiation intensity and the adjustment range, irradiance instability, irradiation uniformity and beam collimation of .the sun simulator and analysis the performance are researched importantly by large number of test data.Shaping speetural is produced by xenon with filter.. The stability of low irradiance by optical attenuators and the irradiation uniformity are improved by xenon lamp and optical integrator projection lens defocus. The results show that the solar simulator with meteorological moni- toring spectral match to standard of AM1.5, the irradiation intensity in the range of 100~1250W/m2 is continuously ad- justable, irradiation instability reach＋1%, irradiation non uniformity reach ±1% and ±2% within φ100mm and φ200mm. It has been put into the use of the National Meteorological units which can meet the detection requirements of meteoro- logical radiation measuring instrument.
