This paper evaluates a method to obtain the slope-corrected normalized radar cross section (σ0) using SAR interferometry. An error model on a slope correction factor has been derived as a function of a scene coherence and a baseline distance. The model has been verified using JERS-1 SAR data and a ground terrain model. Analyses have shown that the proposed method can correct the radiometric slope effect within an accuracy of 0.3 dB if the interference condition is satisfied
