Extended Space Doppler Adaptive Processing for Bistatic Multichannel ISAR imaging of targets masked by strong clutter

SAR systems are unable to obtain well focused images of non-cooperative targets in the scene. Moreover, the spreading effect induced by the uncompensated target motion leads to low detection capability. For this reason clutter suppression techniques are needed to improve target detection. This make ISAR processing applicable to obtain well focused images of non-cooperative moving targets. In order to apply this processing to bistatic system the problem of clutter non-stationarity should be taken into account since this dramatically degrades STAP performance with respect the monostatic case. A new bistatic STAP processing will be introduced and ISAR processing will be applied after clutter suppression. Results on simulated data will prove the effectiveness of the proposed approach.
