In this paper, a fast imaging algorithm based on the layered Green's function is applied to generate images of planar stratified media. Imaging results with a gap between blocks inside the wall are analyzed based on different polarizations. 2D FDTD simulations and measurements are used to generate near-field synthetic aperture backscatter data.
An efficient algorithm is proposed to reconstruct the 3D image of objects embedded in a multi-layered medium. Under the first-order Born approximation, the spectral domain dyadic Green's function for an arbitrary layered medium is used to obtain a linear relation between the spatial Fourier transform of the object function and the scattered field. The algorithm is efficiently implemented using the...
Based on the Crescent Vector single-frequency and single-system testing OEM board with external GPS twin antennas to achieve real-time attitude determination. Take aerial photogrammetry for example, built a GPS twin antennas real-time yaw angle correction system based on MUC. The System acquires data through the OEM board, and real-time control the DC motor by the MCU to real-time achieve the correction...
