| Description | A novel passive radar device developed by project partner University of Birmingham was tested in a series of experiments to assess its range, precision and accuracy. The intended application for the device is to measure ground movements over large areas due to landslides, tunnelling, and mining. The experiments were calibrated using more conventional laser scanning approaches. Further experiments were carried out to assess the likely error in displacement results caused by seasonal changes in vegetation cover, and the method of mapping the ground surface. The error from the former could be significant, and a method of estimating the true ground surface from information about the vegetation cover was proposed. |
| Exploitation Route | The passive radar device needs further development before it could be used as a commercial system for measuring ground movements. The research relating to the errors associated with vegetation and mapping of the ground surface have wider application and have been published as journal contributions. |
