Video synthetic aperture radar (VideoSAR) technology, which has fine resolution and high frame rate, is used to obtain the dynamic information of the observation scene. However, the height information of the target produces some additional offsets of target location in the digital elevation model under multiangle VideoSAR image sequence. This study analyses the reason for the target location displacement in VideoSAR, which includes the deduction of the mathematical relation between the location displacement and VideoSAR imaging geometry, as well as the influence of target height. Finally, the simulation results validate the theoretical analysis.
