The Free Interpolation Three-Dimensional Imaging Algorithm Based on Non-Uniform FourierTransform
Aiming at the problem of large interpolation calculation error in the wavenumber domain convolution integral holographic three-dimensional imaging algorithm in the near range microwave synthetic aperture radar (SAR) three-dimensional imaging algorithm, a free interpolation three-dimensional imaging algorithm based on Non-Uniform Fourier Transform (NUFFT) is proposed. The algorithm has the advantages of real-time, small error, suitable for engineering realization. In the semi-physical simulation system, using the standard target, the imaging quality and the amount of calculation are analyzed and verified, the effectiveness and feasibility of the algorithm are verified.
