Scalar magnetometers and Time-Domain Electromagnetic TDEM systems are proven and effective technologies used extensively in the field to detect, discriminate and classify unexploded ordnance UXO. These two methods complement each other with magnetometers being excellent at detecting large and deep ferrous targets but having limited discrimination capability while the opposite is true for TDEM systems. A combined magnetometer-electromagnetic system is ideal for UXO remediation. However, without complicated interleaving method, it is not possible to simultaneously run both sensors in the close vicinity to each other due to the interruption of the magnetometer operation by the electromagnetic EM pulses. Our objective is to enable integration of miniature laser-pumped cesium magnetometers with TDEM systems by improving the magnetometer sensor to function in presence of an EM transmitter.
