摘要：
Spotlight Synthetic Aperture Radar (SAR) is an imaging mode with high resolution and widely used in spaceborne and airborne platforms as well as the platform in near space-a new position in space. In this paper, a new algorithm, Range Migration Sub-aperture Algorithm (RMSA), is proposed which is applicable to the spotlight SAR imaging mode in near space. It can reduce the limitation of Pulse Repetition Frequency (PRF) and radar power, and solve the problems of spotlight SAR in near space such as overlong synthetic aperture, motion error, etc. And through the simulation and contrast, the algorithm is verified to be effective.
