ChirpScaling算法是一种高效、高精度的SAR成象处理算法,算法解决了在宽天线波束或者天级高斜视角情况下获得高分辨力图象的问题。本文在ChirpScaling算法的基础上,提出采用新的结构和新的相位函数来接纳机载SAR成象处理所需的运动补偿相位,使得ChirpScaling算法成为机载前斜视SAR的一种实用的、高效算法.本文给出了一幅采用该算法处理的德国宇航院(DLR)的E-SAR图象,证实了该算法的可行性。
The ChirpScaling algorithm is an efficient and highly accurate SAR imaging algorithm that solves the problem of obtaining high-resolution images with wide antenna beams or sky-high sky-squint angles. Based on the ChirpScaling algorithm, this paper proposes a new structure and a new phase function to accommodate the phase of motion compensation needed for airborne SAR imaging, making ChirpScaling algorithm a practical and efficient algorithm for airborne SAR . In this paper, we present an E-SAR image of German Aeronautics and Space Administration (DLR) that is processed by this algorithm, which proves the feasibility of this algorithm.
