Modelling an Airborne Time-Domain Electromagnetic (TDEM) System using a Novel Integral Formulation

时域电磁（TDEM）系统是用于探测电磁场的仪器，在其他应用中，用于测量地球外壳深处发现的矿藏产生的微弱信号。这种探测是通过发射与这些沉积物相互作用的非常强烈的时变电磁场来实现的。反过来，土壤的电磁响应在探测装置内诱导出比背景或仪器噪声更大的信号。因此，它们可以被采矿业用作矿物性质和数量的指纹。话虽如此，很明显，为了正确解释数据，必须采用物理上一致的模型。在此建议的背景下，将使用一种新的积分方法来模拟位于地球表面以下数百米的矿床的电磁响应。这个模型将帮助地球物理GPR国际公司（aquacimac公司）考虑到土壤电导率的局部变化，从而改进他们当前的计算模型。一旦该方法得到充分执行，预期它将有助于探地雷达的业务，从而有助于加拿大采矿业的发展。

Time-Domain Electromagnetic (TDEM) systems are instruments designed to detect electromagnetic fields andare used, among other applications, to measure weak signals generated by mineral deposits found deep withinthe Earth's shell. This detection is achieved by emitting very intense time-varying electromagnetic fields thatinteract with these deposits. In turn, the soil's electromagnetic response induces, within a detection device,signals that are greater than the background or instrumentation noise. Therefore, they can be used by the miningindustry as a fingerprint of the nature and quantity of minerals. That being said, it is obvious that in order toproperly interpret the data, a physically-coherent model must be employed. In the context of this proposal, anovel integral method will be used to model the electromagnetic response of mineral deposits located at severalhundred meters beneath the Earth's surface. This model will help Geophysics GPR International Inc. (aQuébec-based company) take into account local variations in the soil's electrical conductivity and consequentlyrefine their current calculation model. Once the methodology will be fully implemented, it is expected that itwill help GPR's operations and consequently contribute towards the development of Canada's mining industry.
