Abstract
Magnetometry and pulsed electromagnetic radiation (EM) may be employed during a same survey pass by synchronously interleaving the collection of magnetometer data with pulses from EM sensors. For example, one or more magnetometers may be sampled between pulses of one or more EM coils such that the data from the one or more magnetometers is substantially free of artifacts from the pulsed EM radiation. A detection system may include a vehicle capable of locomotion over a surface of earth, a mount coupled to the vehicle, the mount including at least one magnetometer, at least one EM sensor adapted to produce pulses of EM radiation, and a controller adapted to interleave collection of data from the at least one magnetometer between the pulses of EM radiation.
