Abstract

Tomographic imaging deals with reconstructing an image from its projections. In the electromagnetic field, cross-range projections can be obtained from a spectral analysis of the radar echoes of a rotating target. However, the lack of resolution of classical methods like the Fourier transform leads to very poor quality images. We thus couple a proposed high resolution spectral analysis method with the backprojection algorithm. We illustrate the efficiency of the whole method on a measured radar echo of a target
