A Corrected Engineering Estimation Formula of Radiometric Resolution in SAR Images

该文分析了合成孔径雷达图像辐射分辨率的本质,指出了目前工程应用的合成孔径雷达图像辐 射分辨率估算值存在着较大的误差,只适合于定性分析。在利用信号检测错误概率的基础上推导出了适合于 定量分析的合成孔径雷达图像辐射分辨率工程估算公式.

After analyzing the inherence of radiometric resolution in SAR images, this paper points out there is considerable error of radiometric resolution in SAR images using current engineering estimation formula which only suits for the qualitative analysis. Based on probability of error in the theory of signal detection, an engineering estimation formula of radiometric resolution in SAR images is derived. The corrected formula suits for the quantitative analysis.
