Abstract�� In view of the current trend of space-borne synthetic aperture radar (SAR) developed toward to the high-resolution, multi-mode direction, considering the characteristics of space-borne SAR system in various modes. The integration indicator system of space-borne SAR system was sumd up. Based on the indicator system, a designing method of high-resolution, multi-mode SAR system was proposed, and the integration system designing flow was given. The analysis was focused on radar antenna design parameters, radar system design parameters, radar transmitter power selection. The method was validated by taking an example for a foreign high-resolution, multi-mode SAR system. Based on overall technical indicators and orbital parameters of the example system, the central electronics equipment parameters, antenna parameters and beam position parameters were designed, and the system performance was analyzed. The designing method overcomes the limitations of current methods and provides technical support in the development of high-resolution, multi-mode space-borne SAR system.
