Groundradar has recently visited Estonia to take delivery of a custom dielectric permittivity probe, which is also capable of providing electrical conductivity and soil moisture readings. As the potential applications for Groundradar’s proprietary long-range GPR instruments grow, traditional limitations on suitable GPR survey locations are increasingly challenged. Groundradar will use the new probes at a variety of new application sites worldwide to test parameters critical to the prediction of radar performance. Clients may now employ this instrument prior to Groundradar’s mobilisation to provide critical measurements which Groundradar will use to determine the maximum predicted range and resolution of a survey, as well as the most suitable radar system for the task.
