Interferentce on airborne communication system caused by electrical system of UAV platform is studied. Based on the study of electrical system of UAV platform and with channel simulation meth-od, the interference path of electrical system of UAV platform is analyzed. On this basis, this paper proposes a fast and efficient interference source positioning method and corresponding remedial scheme. And in light of actual environment, a simple and effective EM retify-and-reform measure is also formulated. Experiment results show that the interference of the electrical system of UAV platform is reduced by more than 30dB. Receiving background noise of airborne communication device of UAV platform decreases from the previous-52 dBm to the present-87 dBm, and finally the requirement of wireless communication is satisfied.
