Towards the CNN-based detection of disturbing objects in multi-channel GPR data

, 2022
A Ground Penetrating Radar (GPR) is an active sensor system, which enables the detection of buried objects interacting with the radar signal. Detectable objects can be of man-made (e.g. pipelines) or natural (e.g. stones) origin.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...
