摘　　要：地面辐射场地定标对于提高辐射定标精度具有重要意义,尤其针对没有星上定标设备的卫星遥感器,而决定场地定标精度的重要因素之一即为场地的光学、地表、气象条件等特性。介绍了定标场地选择标准及评价因素、国内外主要定标场地特性及其比较,并分析总结了这些场地的利弊,探讨了今后外场辐射定标场地建设、辐射定标精度的提高及做法。Ground radiation calibration site is useful of the radiometric calibration accuracy, especially for haven＇ t onboard calibration equipment. The calibration accuracy is decided to the optical, surface, weather conditions and other characteristics of the site. The basic selection criteria and evaluation factors of site, characteristics and comparisons within domestic and foreign major site are all de- scribed, and the advantages and disadvantages of these sites are analyzed and summarized. Finally, the approach to improve the accu- racy is discussed in the future.
