In the work, for the first time the problem of synthesis algorithms of optimal and quasioptimal radiometric signal processing for restoration of radiometric images in ultrawideband radiometers with a multi-antenna array is solved. The potential accuracy of estimation is calculated. It is shown that the quasioptimal algorithm is close to the algorithm realized in the aperture synthesis systems and used in radio astronomy.References
