A method employs an unmanned aerial vehicle to carry an electromagnetic field measurement system to overcome environmental obstacles in measuring environmental electromagnetic field. The electromagnetic field measurement system senses the electromagnetic field of a spatial position in the environment to generate a sensing signal, then processes the sensing signal to remove the high-frequency electromagnetic interference generated by the operation of the unmanned aerial vehicle itself from the sensing signal, and converts the processed sensing signal into a digital signal. The digital signal is processed to extract at least one wave according to a fundamental frequency and a harmonic order, thereby removing the low-frequency electromagnetic interference from the digital signal. The extracted wave is employed in calculating an environmental electromagnetic field value of the spatial location.
