In this paper the problem of compensating of effects of destortion of a spaceborn SAR signal owing to ionospheric propagation effects in P, VHF bands is considered. The algorithms of blind reconstruction of SAR images, based on minimum entropy method (ME), for cases nonparametric indeterminacy are offered. Some results of mathematical simulation are presented.
