摘要：
In this paper a three-dimensional (3D) diffraction tomographic (DT) algorithm is proposed for real-time through-the-wall imaging (TWI). The spectral expansion of the three-layered medium dyadic Green's function is employed to derive a linear relation between the spatial Fourier transforms of the image and the scattered field. Then the image is efficiently reconstructed with inverse Fast Fourier Transform (IFFT). The linearization of the inversion scheme with Born approximation and the easy implementation of the algorithm with FFT/IFFT make the DT algorithm suitable for on-site TWI applications.
