A soft 3D reconstruction algorithm for non cooperative moving targets is proposed in this paper. This method exploits a dual interferometric ISAR system (InISAR) to estimate the heights of the dominant scatterers with respect to the Image Projection Plane (IPP). In particular, the interferometric phases measured from two orthogonal baselines are used to reconstruct both the third dimension from 2D-ISAR images and the IPP. A Cross-Channel Coherence-based detection is used in order to take into account only the areas of the target with meaningful interferometric phase. In order to verify the effectiveness and the reliability of this technique, a Multi-Channel ground-based radar has been used.

Abstract
A soft 3D reconstruction algorithm for non cooperative moving targets is proposed in this paper. This method exploits a dual interferometric ISAR system (InISAR) to estimate the heights of the dominant scatterers with respect to the Image Projection Plane (IPP). In particular, the interferometric phases measured from two orthogonal baselines are used to reconstruct both the third dimension from 2D-ISAR images and the IPP. A Cross-Channel Coherence-based detection is used in order to take into account only the areas of the target with meaningful interferometric phase. In order to verify the effectiveness and the reliability of this technique, a Multi-Channel ground-based radar has been used.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
