    摘要:

    合成孔径雷达(SAR)具有高分辨率、全天候等优点,是提高精确制导武器制导精度的有力工具。制导精度是精确制导武器的重要性能指标,影响SAR制导系统精度的主要因素有实时图的获取误差及预处理误差、图像匹配误差、惯导测量误差、SAR制导特殊弹道引起的导航制导的误差。概述了SAR图像匹配制导系统精度的相关研究,对比和分析了这些研究和结论,指出了该研究存在的问题和发展方向。

    Abstract:

    Synthetic aperture radar (SAR) has the advantages like high resolution, all-weather and so on. It is considered to be a powerful tool to improve guidance accuracy of precision gaided weapon. Guidance precision was an important performance measurement of precision-guided weapons. The main factors affect the accuracy of SAR guidance system are scene matching errors, real-time imaging acquisition and pretreatment errors, inertial measurement errors, navigation guidance errors caused by the SAR guidance trajectory. The studies on SAR guidance accuracy of the influencing factors were described. The research and the conclusions were comparied and analized. The existing problems in the research and development direction were pointed out.
