Abstract

The paper is concerned with high resolution microwave imaging of targets rotating in a small azimuth angle range. An unified formulation for image reconstruction is derived

which is applicable for all bi-static

mono-static

near-field and far -field imaging geometries. The superresolution imaging techniques are discussed and a new image reconstruction algorithm

which combines the spectral extrapolation with the use of coarse shape information derived from the imaging measurement data

is suggested. Lastly

the imaging results obtained in an anechoic chamber and related conclusions are given.
