This paper describes the characteristics of the on-axis TMA optical system. An on-axis TMA system with 13m focal length is designed and analyzed. To solve the initial configuration parameters  Cassagrain structure is confirmed firstly  and then the tertiary mirror. Based on initial configuration parameters  automatic optimization is executed in ZEMAX program  and design result with excellent image quality is acquired  which shows the procedure we choosed with good advantage of computer processing. As the distortion of the design reaches 1%  its influences on TDICCD brushing camera are discussed. The source of distortion is analyzed and correcting methods are considered. Zero focal power corrector is chosen to correct the distortion  and the corrected distortion is less than 0.02%. The research on on-axis TMA system in this paper makes a foundation for farther high-resolution remote sensing applications.
