Electromagnetically detecting thin resistive bodies in shallow water and terrestrial environments
A technique includes using a first sensor to perform a first electromagnetic field measurement to obtain first data, which is indicative of the presence of a resistive body. The first data is relatively sensitive to an effect that is caused by an air layer boundary. The technique includes using a second sensor to perform a second electromagnetic field measurement to obtain second data, which is indicative of the presence of the resistive body. The second data is relatively sensitive to the effect, and the first and second sensors are either both magnetic field sensors or both electric field sensors. The technique includes combining the first and second data to generate third data, which is relatively insensitive to the effect and is indicative of the presence of the resistive body.
