Simulation of ISAR imaging of moving targets

The simulation of inverse synthetic aperture radar (ISAR)imaging of moving targets is described and the effects of the target's rotations on ISAR imag ing are analysed. The simulation of ISAR imaging of an aircraft with a circ ular motion is demonstrated. An ideal ISAR image of a target can be derived by projection of the target onto an image projection plane. Time-varying D oppler shifts induced by roll, pitch and yaw motions are analysed using the rotation matrix and the effective rotation vector. Through the simulation, the individual effect of roll. pitch and yaw motion on ISAR imaging is obs erved and studied.
