Ground Penetrating Radar
When I first saw this, I wondered where the grass-collector was attached. And then I realised it is a very up-to-date ground penetrating radar set.
GPR is used in this geophysical survey to identify sub-surface changs in th soil structure, and particularly to identify buried wooden structures. The Roman fort is believed to have been mainly a wooden structure, and some elements have been provisionally identified.
