  • 简述了高层大气风场被动式遥感探测的基本原理;论述了新型风成像干涉仪宽场、消色差、温度补偿理论,针对目前国际上采用的风成像干涉仪补偿方法的不足,从理论上进行了分析与讨论,给出了四层介质的优化补偿理论和方案.模拟结果表明,该补偿可完全理想地消去单色光的温差,且复色光的温差补偿要比现有的方法提高1—2个量级.该研究为设计宽场、消色差、温度补偿的新型风成像干涉仪和提高风场探测精度提供了重要的理论依据和实践指导.

     

    The basic conditions for designing a wide field Michelson interferometer with chromatic and thermal compensation, which is used to measure the upper atmospheric wind field,is briefly described. Comparing with the current method for designing the wide field Michelson interferometer with chromatic and thermal compensation, we present a method uses four media for the compensation of the MI to eliminate the monochromatic thermal aberration. The result shows that, by using this method, the polychromatic thermal aberration is ten to hundred times smaller than the method now in use. The research has important theoretical significance and practical value both for the research and development of the wide field Michelson interferometer with chromatic and thermal compensation for detection of the upper atmospheric wind field.
