An aviation geological detection method applied to the geological detection instrument based on the unmanned aerial vehicle as claimed in any one of claims 1 to 8, wherein the geological detection instrument based on the unmanned aerial vehicle comprises an unmanned aerial vehicle, and a signal transmitting coil, a receiving coil, a signal collector, a multistage amplifier, a compensating coil and a signal processor which are arranged on the unmanned aerial vehicle, and is characterized by comprising the following steps of:
Transmitting a group of square wave current signals to a region to be detected by using a signal transmitting coil;
the receiving coil is used for receiving magnetic field changes caused by square wave current signals according to the area to be detected to form induced electromotive force;
the signal collector is used for collecting the induced electromotive force;
Amplifying the acquired induced electromotive force by using a multistage amplifier;
receiving the signal amplified by the signal processor and converting the received signal into geological data;
the direction of the current signal which is introduced into the compensation coil is opposite to that of the current signal which is introduced into the signal transmitting coil.
10. A computer readable storage medium having stored thereon a computer program, which when executed by a processor implements the airborne geological detection method as claimed in claim 9.
