A Corrected Engineering Estimation Formula of Radiometric Resolution in SAR Images
合成孔径雷达图像辐射分辨率工程估算公式的校正

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.
