OPTIMUM ALGORITHM FOR ESTIMATING RADIO BRIGHTNESS IN SPATIALLY DISTRIBUTED RADIOMETER SYSTEMS
RESUMO
Optimization of the radio thermal radiation noise processing in multichannel spatially distributed radiometer systems is performed. The algorithms consideration is applicable in the aperture synthesis systems. The maximum likelihood method is implemented for calculation in the assumption that spectral brightness of radiation is constant within the frequency band of receiver, whereas the image of a radiating object depends on spatial (angular) coordinates. The peculiarities of solved tasks consists in using the spectral FV -transforms which do not require execution of the spatiotemporal band-limitedness (the quasi-monochromatic approximation) condition and make it possible to solve the problem of synthesis of algorithms for processing wideband and ultra wideband signals.
