The development of spaceborne Synthetic Aperture Radar(SAR)technology declares that the golden era of SAR remote sensing in archeology is approaching;however,nowadays its methodology framework is still lacking due to the inadequate case studies validated by ground-truths.In this study,we investigated the crop marks using multi-temporal Cosmo-SkyMed data acquired in 2013 by applying a twostep decision-tree classifier in conjunction with a spatial analysis in an area of archeological interest nearby the archeological site of Han-Wei capital city(1900–1500 BP),in Luoyang,China.The time-series backscattering anomalies related to the wheat growth cycle were identified and then further validated in two zones by geophysical investigations(Ground Penetration Radar and electrical measurements)and in a third zone by archeological excavations made after the SAR data acquisition.This study provides a new approach for the relic detection,shallowly buried and covered by the crop vegetation,by temporal crop marks on spaceborne SAR images.We also emphasize the necessity to establish a satellite-to-ground methodology framework for the promotion of remote-sensing technology in archeology. 展开更多
