| description | The invention discloses a multi-source short-offset frequency domain electromagnetic detection method, which comprises the following steps: different transmitting sources are sequentially arranged in different positions of the observation point, and the distance between the transmitting source and the observation point is 1 to 3 times the detection depth, and the transmitting signals of different frequencies are transmitted from the source, the horizontal electric field component is observed at the receiving point, and the signals excited by different transmitting sources observed at the same measuring point are jointly inverted to obtain the underground electrical structure. The invention proposes a frequency domain electromagnetic method using multiple transmitting sources for joint detection, and shortens the observation offset to 1 to 3 times the detection depth, which can significantly improve the strength of the observation signal and the recognition accuracy of underground targets. |
