Abstract :
The main problems of automatic stereo-radargrammetry are analyzed. An algorithm for reconstruction is presented including an alternative formulation for the restitution function. The authors present a few experimental results and emphasize on some of the difficulties encountered during the matching process. They show that these difficulties are due to the correlation function. Some solutions are proposed and discussed
