Abstract:

Based on the signal model of multi-baseline synthetic aperture radar (MB-SAR), the matrix function between the observed samples and the image in the height direction is obtained, and QR decomposition is used to solve the matrix equation.The 3D imaging algorithm based on QR decomposition for MB-SAR is established, and the simulation results are presented.

Key words: multi-baseline SAR, 3D imaging, QR decomposition
