 Radar sequences can be obtained from [Oxford Radar RobotCar Dataset](https://oxford-robotics-institute.github.io/radar-robotcar-dataset/datasets) and should be placed in the `./data` folder. The folder organization listed as `full_seq_1` is an example of how the directory looks like, and is taken from the [`10-11-46-21` sequence](https://oxford-robotics-institute.github.io/radar-robotcar-dataset/datasets/2019-01-10-11-46-21-radar-oxford-10k).
