This article presents a new method to retrieve dynamic information from spaceborne Doppler radar observations. The method is based on a complex convolution Doppler resampling (CConDoR) formulation, which links the spaceborne pulse-pair (PP) correlation measurements to high-resolution PP products that are not affected by the spacecraft motion. The CConDoR formalism allows to easily simulate Doppler products via convolution products. The CConDoR representation enables also retrievals by deconvolution. This approach is illustrated using a Wiener deconvolution algorithm. Results are shown for simulations of the radar of the Earth Cloud Aerosol Radiation Explorer (EarthCARE; developed by the European and Japanese space agencies). The proposed corrections improve the accuracy of the measured mean velocities (by correcting for nonuniform beam-filling (NUBF) biases) and spectral widths (by correcting for the spectral broadening), which to the best of the authors’ knowledge is novel.

星载多普勒雷达测量的动态反演：CConDoR 方法


本文提出了一种从星载多普勒雷达观测中检索动态信息的新方法。该方法基于复杂的卷积多普勒重采样 (CConDoR) 公式，它将星载脉冲对 (PP) 相关测量与不受航天器运动影响的高分辨率 PP 产品联系起来。 CConDoR 形式允许通过卷积积轻松模拟多普勒积。 CConDoR 表示还可以通过反卷积进行检索。该方法使用维纳反卷积算法进行说明。显示了地球云气溶胶辐射探测器（EarthCARE；由欧洲和日本航天局开发）雷达的模拟结果。所提出的校正提高了测量的平均速度（通过校正非均匀光束填充（NUBF）偏差）和谱宽度（通过校正谱展宽）的准确性，据作者所知，这是新颖的。
