摘要
在航空电磁实际勘查中,有较多因素影响系统的勘探精度和分辨率。这里以Aer-oTEM系统为例,基于MAXWELL软件正演模拟算法,对异常体横向距离变化、异常体倾角变化及异常体埋深变化对电磁响应曲线的影响进行分析。正演模拟结果表明:时间域直升机航空电磁系统具有较高的横向分辨率,对不同倾角的异常体都有较好的响应以及具有较大的勘探深度。
There are many factors to affect the helicopter TEM exploration accuracy and resolution in the actual exploration.We used the MAXWELL software to do the forward modeling to discuss the characteristics of AeroTEM system by changing the horizontal distance of the anomalous body and changing of the anomalous body angle and changing of abnormal body depth to analyze the influence of the electromagnetic response curve.The results show that the helicopter timedomain airborne electromagnetic system has a high lateral resolution and good electromagnetic responses of abnormal body morphology.
