  • This paper introduces a multiscale maximumentropy image reconstruction algorithm for twodimensionalsynthetic aperture imaging radiometers. Thenovelty of the method is to use wavelet decomposition tocontrol the noise amplification in the different scales. Andour work is focused on the application and the adjustmentof the Maximum entropy method (MEM) to the Earthobservation situation. Several numerical simulations havebeen performed for synthetic aperture imaging radiometersin the Geosynchronous Earth orbit (GEO). The simulationresults indicate that, with the proposed method, itis feasible to improve the spatial resolution of the reconstructedimage while preserving the radiometric sensitivitysimultaneously.
