Abstract :
A three-dimensional (3D) target reconstruction processing based on bistatic ISAR imaging and interferometry is proposed in this paper. The multi-channel system consists of one transmitter and three receivers in a bistatic configuration. The interferometric phases measured from the receivers lying on two orthogonal baselines are used to jointly estimate the target´s effective rotation vector and consequently the image projection plane (IPP). Then, the heights of the scattering centers with respect to the IPP are estimated. Finally, numerical simulations are carried out in order to evaluate the proposed method´s performance.
