%X 3D reconstruction of targets in Interferometric SAR (InSAR) refers to determine target's 3D position based on principal measurements of radar and the InSAR imaging geometry. Several algorithms have been proposed for InSAR. These algorithms rely on simplifying assumptions, such as the flat earth approximation and the plane wave approximation. Significant location errors of targets have been introduced by these approximations. In this paper, a new algorithm is proposed on the models of spherical earth and spherical wave. The solution is given in a closed form only using the measured quantities: orbit parameters, range time, Doppler shift, and interferometric phase. This analytical solution demonstrates more exact than the existing algorithms.
