Abstract :
The superresolution methods described are the linear prediction data extrapolation DFT, the dynamic optimization linear least squares and the Hopfield neural network nonlinear least squares. The live data of a metalized scale model B-52 aircraft mounted on a rotating platform in a microwave anechoic chamber and a flying B-727 were processed by these methods
