摘要
本文介绍了国外无人机SAR/MTI雷达研究现状和发展方向 ,列举了X、Ka、Ku三种频段SAR/MTI雷达主要技术指标 ,重点从工程实现的角度对SAR/MTI雷达技术中若干问题进行了探讨 ,包括无人机、SAR的成像模式和MTI兼容技术、频段选择、SAR成像实时数据的传输方式、惯导系统 ,最后讨论了成像算法。
In this paper, the research and development trend of UAV-borne SAR/MTI radar abroad is introduced, main specifications of three bands, X,Ka and are provided. From the view of engineering realization, problems in the development of SAR/MTI radar are emphtically discussed,including UAV, imaging mode of SAR, compatibility of MTI, frequency band selection, transmission mode of SAR imaging real-time data processing, inertial guidance system, and imaging algorithm of imaging. Finally,imaging algrithm is bronght forward.
