Abstract :
A new solving algorithm in the inverse problem of image reconstruction in microwave imagery, based on the principle of maximum entropy, is developped. The problem is reduced to a solution of a system of differential equations with decided initial values. We must choose the initial values so that the contraints are satisfied. For illustration, the calculations of a simple object are given. Its results present the influences of the measurement distance and signal to noise ratio on the image reconstruction.
