Summary :

Dependence of SIR-B image intensity on local incidence angles has been investigated to estimate quantitatively topographic effects in SAR imagery. Local incidence angles were computed from a digital elevation model (DEM) produced from a topographical map. Slope images representing the variation of local incidence angles of a hilly area were compared with the SIR-B images. Since the studied area is uniformly covered by shrubs and grass, the topograghic effect can be easily detected. Based on the topographic effects, backscattering coefficients (σ⁰) of the hilly area were estimated and compared with the existing σ⁰ data base.
