Characterization of vibrating targets in bistatic SAR

Motions and micro-motions of objects in an illuminated scene introduces Doppler and micro-Doppler effects in the received echoes. Combining the advantages introduced by the bistatic SAR (BSAR) configuration and the usefulness of the micro-Doppler signature characterization will provide a powerful tool for military and civil applications such as target recognition and classification. In this paper a vibrating micro-Doppler signature for a BSAR system with fixed receiver is analyzed and compared to the signature obtained in a monostatic SAR system. The micro-Doppler effect in a Bistatic SAR system for vibrating targets is analyzed and the derived mathematical model is confirmed with simulations.
