    Abstract
  • Conventional synthetic aperture radar (SAR) has the problems of limited targets' velocity boundary and low accuracy. To solve the problem, this paper introduces a new mode Hybrid-TOPS to detect moving target. Firstly, the SAR imaging mode was represented quantitatively through hybrid factor. Employing hybrid factor, a new mode for moving target detection was proposed by the combination of TOPS and inverse TOPS. This mode can not only realize repeated observations in the same area, but also has the ability of continuous observation in azimuth. Moreover, sequential SAR images were able to be obtained by taking advantages of hybrid TOPS combination. Secondly, through image registration and parameter inversion based on the new mode, moving target's azimuth information can be obtained. Finally, the simulation results justify the superiority of the new mode and the extracting accuracy in movement information.
