A novel stereo positioning method based on optical and SAR sensor

This paper investigates the joint use of SAR image and optical image for stereo positioning. To obtain the 3D information of target in the real scene, the geometric relationship between optical radar and SAR are initially established. Then, two angle equations of optical data and a slant range equation of SAR data are jointly utilized to derive the 3D coordinate of target. To further analyze the impact of uncertain measurer errors such as range measurement, orbit, and angle measurement on the novel location model, the partial derivatives of resultant elevation are mainly discussed. Finally, computer simulations are provided to show the error range of the proposed method according to different measurer errors.
