Abstract
Ground penetrating radars with a continuous frequency-modulated probing signal are widely used to detect near-surface and shallow objects. Their operation requires near-field operation in the presence of powerful interfering reflections from the boundary of the host medium, which mask the response from objects in nearby resolution elements and complicate their detection. To address this issue, this article proposes a method for compensating for interfering reflections from the boundary of the host surface in a radar detector of shallow objects using a frequency-modulated probing signal. The results of experimental testing of this method are presented, allowing for improved performance of ground penetrating radars with continuous frequency-modulated radiation in detecting near-surface and shallow objects.
