Abstract:
Exploration for targets at depth or targets obscured by conductive overburden have historically been a challenge with airborne EM methods. Although modern systems have been improved with greater primary transmitter moments, noise from receiver coil motion in the Earth’s ambient field limits detection of secondary target signals, especially in late time. The new Helitem² system uses a patented low-noise receiver and a 50% duty cycle square pulse transmitter waveform to achieve increased signal detectability for deep and covered targets.
