Paper Abstract

Theoretical problems are discussed and experimental results are presented with regard to the recording of large holograms of moving objects by the aperture synthesis method at optical wavelengths. It is shown, that for the recording of a hologram by a linear array of unphased coherent receivers, the phase distortions of the signal field can be compensated by a post- detector signal processing, based on the construction of joint statistical estimates of the phase distortions and the image of the object. As a result of the processing of the recorded holograms, an image of various distant extended objects is obtained with very high angular resolution.
