摘要: 該文分析了合成孔徑雷達(dá)圖像輻射分辨率的本質(zhì)，指出了目前工程應(yīng)用的合成孔徑雷達(dá)圖像輻 射分辨率估算值存在著較大的誤差，只適合于定性分析。在利用信號(hào)檢測(cè)錯(cuò)誤概率的基礎(chǔ)上推導(dǎo)出了適合于定量分析的合成孔徑雷達(dá)圖像輻射分辨率工程估算公式。

Abstract: 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. -
