摘要：Up till now it is still difficult to acquire stereoscopic space-borne image pairs of some area due to climate condition or atmosphere pollution. This paper describes the geometric aspects and the mathematical treatment for the stereoscopic image pair composed of optical and SAR space-borne images in positioning. First, the geometric equation for linear array push-broom imagery and F. Leberl model for SAR imagery as well as methods to simultaneously determine or refine individual parameters of these models are briefly reviewed. And a straight-forward single-step procedure has been developed which follows the philosophy of photogrammetric bundle adjustment techniques. Secondly, from these imaging models of one optical and SAR image, the composite stereoscopic pair is constructed. The stereo positioning is the process of determining the ground coordinate of a ground point from a pair of homologue points in the composite stereoscopic pair. Experimental results show that it is feasible to construct stereoscopic pair with one optical and SAR image, of which the average positioning RMS value is close to stereoscopic pair with optical/optical or SAR/SAR images
