A new simulation method based on continuous tangent motion model for spaceborne high-resolution SAR

This paper proposes the continuous tangent motion model to discribe the complex relative motion between Synthetic Aperture Radar (SAR) and targets by assuming that SAR moves with an invariant relative velocity vector within one pulse repetirion interval (PRI) along a tangent segment. And an effient and accurate simulation method is constructed for spaceborne 0.1 m resolution SAR based on the proposed motion model. The simulation results well validates that the novel mothed simulates precisely.
