本文介绍的工作描述了 HITCHHIKER 双基地雷达系统测量的原始数据的信号处理，这是与 TerraSAR-X/TanDEM-X 系统合作的混合（星载/静止）实验中获取的原始雷达数据公开发布的最后一步。在预处理过程中，传感器存储的数据被转换为可以用广义信号模型描述的通用数据集。因此，本步骤进行发射机和接收机的同步、位置预处理和脉冲压缩。此外，预处理的雷达数据集中在空间域中，产生双基地雷达坐标中的合成孔径雷达（SAR）图像。最后，描述了数据集的结构和格式以及请求它们的过程。
The work presented in this paper describes the signal processing of raw data measured by the HITCHHIKER bistatic radar system which is the final step toward open publication of the raw radar data acquired in the hybrid (spaceborne/stationary) experiments in cooperation with the TerraSAR-X/TanDEM-X system. During the preprocessing, the data stored by the sensor are transformed to a generic dataset which can be described by a generalized signal model. Therefore, the synchronization of transmitter and receiver, the position preprocessing, and the pulse compression is performed in this step. Furthermore, the preprocessed radar data are focused in spatial domain yielding synthetic aperture radar (SAR) images in bistatic radar coordinates. Finally, the structure and format of the datasets are described along with the procedure to request them.
