Abstract

The problem of high resolution imaging for field visualization is considered. An iterative method of optical data processing is presented in the paper. The problem of resolution enhancement is considered as image reconstruction that includes the solution of an inverse ill- posed problem. The method proposed makes use of the iterative technique and adaptive regularization procedure to improve image quality. Nonlinearity of the method is provided by a nonnegative constraint and a spatial limitation on the probable image extent that makes it possible to accomplish band-limited extrapolation and enhance the resolution.
