Accurate profile reconstruction using an improved SAR based technique

An advanced SAR processing method featuring two new approaches is proposed. First, the combination of the phase and amplitude of the SAR image is used to create an initial guess of the possible positions of the contour facets. Second, a virtual focusing of the field scattered by the geometry under study is used to interrogate isolated sections of the contour to be reconstructed, decreasing the computational cost and ambiguity of the reconstruction problem. It is shown that this processing increases the resolution of any SAR based system without increasing the necessary bandwidth.
