A high-resolution radar for detecting subsurface objects is under development at the Electromagnetics Institute, Technical University of Denmark. The radar differs from those normally used for subsurface probing in that a modulated microwave carrier is transmitted rather than a video pulse. The microwave radar allows for a higher resolution, both vertically and hori zontally, than the video pulse systems presently used, but it has a reduced penetration into the soil (0.5-1 meter).
