机载高分辨率SAR图像直接对地定位原理及精度分析

Principle and Accuracy for Airborne SAR Image Direct Localization

    摘要
  • 摘要: 依据机载SAR成像的原理,给出了一种实用的机载SAR直接对地定位公式,并结合获取的高分辨率图像进行了定位纠正,取得了较好的效果。根据机载SAR图像对地定位的原理,推导了定位误差的传播公式,并进行了一些误差模拟研究

     

    Abstract: A practical localization formula is given in the paper on the basis of the principle of airborne SAR imaging. This method is used to rectify the 0.5m airborne image and the result is satisfactory. The error of SAR image localization is also proposed according to the error propagation law and some conclusions are drawn based on some error simulations.
