Wavelet Interpolation Algorithm for Synthetic Aperture Radiometer
In this paper,we propose a wavelet-based-interpolation algorithm,which improves the effect of Fourier image reconstruction for 2_D synthetic aperture radiometer. The core idea is to get the VF (Visibility Function) data on grid points by using the interpolation algorithm. Along with the problems that Fourier transform meets being solved, the reconstruction precision improved. Comparing with the traditional interpolation methods, this algorithm has the advantages to take the correlation of the whole image into account, to keep fine details of the image, and to avoid the saw-tooth and smoothing effects associated with traditional image interpolation techniques. Accordingly,we present experiments to demonstrate the effectiveness of the algorithm.
