Digital Evaluation of Radar Profiles in Peat

摘要

The report is describing the first stage in the development of a system for automatic classifying of radar profiles in peat. First, the different data formats are described, and also how the conversion between analogue and digital form was made. The construction of a synthetic radar profile is hereafter described. The synthetic profile is meant to be used as input, when new algorithms are tested. Here, some of the mathematical methods used are briefly explained. To enhance the digitized signal, a number of digital signal processing methods have been applied. These methods are described and evaluated. Both time domain methods and frequency domain methods have been used. To enhance spatial features in the profile, a two-dimensional approach is made. Algorithms for bottom tracking and correction of topography are also dealt here. After evaluation and conclusions, the outline of continued project is suggested. (ERA citation 13:025739)
