Recently, Bihar Chief Minister Nitish Kumar also visited the discovered archaeological site on the banks of river Chanan and announced to develop the place located in Bhadariya village as a tourist destination.
GPR is a geophysical method that uses a radar pulse to image the upper surface. This non-destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum and detects reflected signals from subsurface structures.
This technique helps in the identification of archaeological sites and their structure, thereby assisting in the interpretation of ancient settlements and man-made structures before possible excavations.
