DOPPLER SIGNAL ANALYSIS OF DRONE ROTORS REFLECTION WITH FRACTAL DIMENSIONS
Краткое описание
The possibility of using the value of the fractal dimension (FD) to analyze the complexity of Doppler signals (DS) at various speeds and the number of rotating rotors of drones is considered. A temporal analysis of the Doppler radar signals during the probing of a multi-rotor drone was performed. Two novel methods for estimating fractal dimensions to assess the complexity of Doppler signals are proposed. It is shown that the values of the fractal dimensions of Doppler signals increase with the increasing rotational speed of the rotor. It has been established that with an increase in the number of rotating rotors, the FD values of Doppler signals depend on the direction of rotation of the rotors and their geometric location. Properties of DS during probing of rotating rotors using phase portraits (PP) constructed with different delay times and the dynamics of changes in the FD values of phase portraits are studied. It is shown that changes in the phase portrait (PP) forms and the FD values of the PP can be used as a recognition feature of multi-rotor drones. A method is proposed for analyzing the complexity of the shape of Doppler signals using fractal dimensions, which allows determining the number of rotors on a drone and estimating their rotation speed.
