| Abstract: |
| 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. |
