摘要

摘要: 针对当前星载合成孔径雷达(SAR,Synthetic Aperture Radar)朝高分辨率、多模式方向快速发展的趋势,兼顾星载SAR系统多种工作模式的特点,总结星载SAR系统的星地一体化指标体系;在此基础上提出了高分辨率、多模式星载SAR系统星地一体化设计方法,给出了系统星地一体化设计流程,对雷达天线参数设计、雷达系统参数设计、雷达发射功率选择进行重点分析;以国外高分辨率、多模式星载SAR系统为例,以其总体技术指标及轨道参数为依据,设计了系统的中央电子设备参数、天线参数及波位参数,并分析了系统的性能,从而对所提出的设计方法进行了验证.该方法克服了现有方法的局限性,为高分辨率、多模式星载SAR系统研制提供了技术支撑.

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.
