摘　　要：由于海洋遥感探测信号的复杂性,在遥感器定标以及遥感产品检验方面强烈依赖海上现场观测数据。因此各国开展了海上定标检验场的建设。文章从全球海上定标检验场的观测技术体系、定标检验场网站点的主要任务出发,对全球海上定标检验场网的现状和发展趋势做了调研,结合中国海上定标检验场网建设的实践和应用,展示了中国海上定标检验场网的建设成果。说明现在中国的海上定标检验场网已经初步具备合理的空间布局、可靠的数据观测等能力,通过未来的发展规划的实施,中国的定标检验场网建设有望提供现场观测的长时间序列的时空立方体数据集。Marine remote sensing satellites,due to their specificity,heavily rely on in-situ marine observation data for the calibration of sensors and the validation of remote sensing products.The complexity of ocean remote sensing detection signals has prompted new demands for ocean observation technology.Under the impetus of spaceborne remote sensing mission requirements,countries have initiated the construction of marine calibration and validation fields.This paper investigates the current situation and development trends of global marine calibration and validation field networks,starting from the observation technology systems of global marine calibration and validation fields and the main tasks of field sites.It showcases the achievements of China's marine calibration and validation field network construction,combining the practices and applications of such networks in China.The current maritime calibration field network in China has initially achieved a reasonable spatial layout and reliable data observation capabilities.With the implementation of future development plans,the construction of China's calibration field network is expected to provide long-term series of spatiotemporal cube datasets for field observations.
