Image Reconstruction: Radio Telescopes
Scientific paper
On basis of numerical experiments the usage recomendations are made of CLEAN-algorithms by reconstruction of two-dimensional brightness distribution with limited numbers of one-dimensional profiles. It is shown that the CLEAN-algorithm with trim-contour is the effective method of solution of the deconvolution problem in this case. The parameters of optimization on the criterium of profiles coincidence are considered. The method of the increase of the standart CLEAN stability is also proposed. The results obtained are useful for image reconstruction on the strip-distribution by lunar occultation, for the processing observational data of radiotelescope RATAN-600 sector, and also by the usage of beavertail beams by remote sensing in tomography. Examples of numerical modeling results are given.
