The single-antenna radio frequency (RF), direction finding (DF) system includes a single-element directional antenna, which is mounted on a multi-rotor UAV (Unmanned Aerial Vehicle) and integrates with a DF algorithm for tracking an RF source in the 2.45 GHz ISM band (or any other frequency band). The algorithm will depend on the rotating nature of the platform to scan the azimuth, as well as several elevation angles with respect to the platform axis of rotation, and thus be able to accurately locate the coordinates of the RF transmitter based on the rec...
1. A single-antenna direction finding system for multi-rotor platforms, comprising: a UAV having multiple rotors, the multiple rotors changing attitude, speed, and direction of the UAV;a direction finding antenna fixed to the UAV;control circuitry operably connected to the multiple rotors, the control circuitry maintaining a desired pitch roll and yaw of the UAV;a direction finding (DF) processor onboard the UAV, the DF processor being operably connected to the control circuitry, the DF processor including: a DF receiver connected to the DF antenna;means...
