菲涅耳望远镜全孔径合成成像激光雷达(简称菲涅耳望远镜)是一种新的高分辨率激光成像技术。在菲涅耳望远镜一维扫描工作模式中,目标和扫描光束的相对运动使得时间-空间变换后的采样信号呈不规则非均匀分布,影响匹配滤波算法中快速傅里叶变换的使用。提出基于重采样插值的菲涅耳望远镜算法,包括时间-空间变换、重采样插值和匹配滤波等主要步骤,其中利用重采样插值将不规则分布的原采样信号转换为正交规则分布的重采样信号。对三种重采样插值方法进行比较,并获得了点目标和面目标的计算机仿真重建图像,证明了算法的有效性。该算法对于菲涅耳望远镜具有实际意义。 Fresnel telescope full aperture synthetic imaging laser radar (referred to as Fresnel telescope) is a new high-resolution laser imaging technology. In the Fresnel telescope 1-D scanning mode, the relative motion between the target and the scanning beam makes the sampled signals spatially and irregularly distributed irregularly, which affects the use of fast Fourier transform in the matched filtering algorithm. A Fresnel telescope algorithm based on resampling interpolation is proposed, including the main steps of time-space transform, resampling interpolation and matched filtering. The resampling interpolation is used to convert irregularly distributed original sampling signals into orthogonal regular distribution resampling signal. Comparing the three resampling interpolation methods, and obtained the point target and surface target computer simulation reconstruction images, and proves the effectiveness of the algorithm. The algorithm has practical significance for Fresnel telescope.
