In this study, inserting moving targets to polarimetric SAR image by Jamming is investigated. In order to insert moving targets in polarimetric SAR image, one has to create same signal on polarimetric SAR by appropriate jamming. So, it is necessary to model obtained signal by radar system when targets which are intended to be inserted is exist. It is known that the delaying times and Doppler shift is function of the SAR system parameters and positions and velocities of spurious targets which are intended to insert. In order to insert big targets such as ship, aircraft that constitute multiple resolution cells can be modeled by multiple point targets which have same velocity and different position according the target shape. Therefore, retransmitted wave is superposition of signals which is obtained for each point targets. We express retransmitted waveform for given imaging scenery and parameters of inserted spurious targets. Proposed method is applied to SAR raw data and moving targets in SAR image obtained successfully.
