Strategy of spectrum reconstruction in stepped-frequency SAR imaging
international radar conference(2015)
摘要
High range resolution of synthetic aperture radar (SAR) can be obtained by using the stepped-frequency technique, but it is still a problem how spectrum reconstruction methods can be combined correctly and effectively with SAR imaging algorithms. This paper analyzes the feasibilities of all the potential combinations between spectrum reconstruction methods and SAR imaging algorithms, and the optimal combinations are proposed. The simulation results verify the analysis in this paper.
