Looking for possible tombstone by using GPR

In March 2020, Dominique Ngan-Tillard and Deyan Draganov were approached by the foundation Jewish Westland, who manages the cemetery in Naaldwijk, and asked whether it would be possible to use non-invasive geophysical methods to look for possible tombstones lying under the ground surface of the cemetery. Because possible tombstones under the surface were expected to be laying not deeper than about a meter, it was decided to use ground penetrating radar (GPR). Due to different factors, including the Covid-19 pandemic, the field measurements at the cemetery were performed at the beginning of August 2020 by Dominique and Deyan. The measured data was processed at the end of August by Frederikke Hansen, an Idea League Applied Geophysics MSc student.
The survey revealed one spot where a buried tombstone is expected and also several anomalies in the shallow subsurface which are worth investigating.

During the work, they were interviewed by the local newspaper (in Dutch):
