Localization of Modulated Signal Emitters Using Doppler-Based Method Implemented on Single UAV

This paper presents the results of the first localization measurements of a radio transmitter emitting modulated signals (e.g., binary and quadrature phase-shift keying or quadrature amplitude modulation) using the Signal Doppler Frequency (SDF) method implemented on a single flying measurement platform. The SDF method is an innovative localization method based on the variation of the Doppler curve, the shape of which is characteristic of the mutual position of the transmitter relative to the receiver trajectory or vice versa. This method could commonly use to determine the position of various radio transmitters. Currently, we are testing the first implementation of this method on unmanned aerial vehicle.
