The Development of the iFTEM Prototype AEM System
The iFTEM airborne electromagnetic (AEM) system is a new fixed-wing, towed-bird AEM system which is being developed for conductivity mapping and the detection of mineral at considerable depths.It filled in the gaps in the fields of the time-domain AEM system in China.This paper presents the design philosophy and describes the design features.The system is now in the initial test-flying stages.The iFTEM system has a high power transmitter that the peak dipole moment is about 500,000 Am2 at 25 Hz.The system bandwidth is from 25 Hz to 20 kHz and the EM sensor is a 3 perpendicular dB/dt air-cored coils in towed bird.As the data acquisition unit can recording full-waveform of the 3-component response and Tx current, the multi-components data can be used to do the bird motion compensation and target geometry discrimination.
