We do not conduct airborne radar measurements. We conducted airborne as well as terrestrial (ground based) laser scanning measurements at Stonehenge and Uppåkra (as well as Birka).
Some of the Uppåkra airborne laser scanning data (LiDAR data) can be seen
here. We actually covered some 40 square kilometres at Uppåkra since I wanted to have as well the connection to the sea (even though it is believed that the prehistoric harbour has been overbuilt by now). The analysis of the LiDAR data from Uppåkra shows old field boundaries, old roads or track ways as well as known and unknown overploughed prehistoric monuments.
Indeed, you find at Uppåkra a mix of Neolithic, Bronze Age, Iron Age, Viking Age and Medieval remains which complicate the analysis. There are strong indications for an army camp from approximately 1644. Do you have any information about any further military camp? One is enough, don’t get greedy
