Imaging radar has been dramatically developed over the past decades enabling a better understanding of cultural heritage from a microwave perspective. Nonetheless, a dedicated survey and analysis of the performance of such technology in cultural heritage monitoring and management is required. In order to fill this gap, we first review the technology advance of imaging radar, including ground penetration radar, ground-based and airborne/satellite radar, in the focused cultural applications to grasp the development trend of these technologies. We then analyse the performance and limitations of imaging radar technologies based on their respective characteristics to facilitate the technology service in practical applications. Finally, we propose a flexible solution of imaging radar in cultural heritage through technical integration with pilot synergy applications in archaeological prospection and cultural heritage diagnosis and conservation.

在过去的几十年中，成像雷达得到了极大的发展，可以从微波的角度更好地了解文化遗产。尽管如此，仍需要对此类技术在文化遗产监测和管理中的表现进行专门的调查和分析。为了填补这一空白，我们首先回顾了成像雷达在重点文化应用方面的技术进展，包括对地穿透雷达、地基和机载/卫星雷达，以掌握这些技术的发展趋势。然后，我们根据成像雷达技术各自的特点，分析其性能和局限性，以促进实际应用中的技术服务。最后，
