Target Signal Separation of Unmanned Aerial Vehicle Group Based on Underdetermined Blind Source Separation
Liang Man · 2023
Cluster operation is an important combat style at present. The attack of UAV (Unmanned Aerial Vehicle) group seriously threatens the safety of air and space defense. The separation of radar echo signal of UAV group is the basis of tracking and identification of UAV. Based on blind source separation method, this paper studies the separation of UAV group radar echo signals. First, the period of each UAV echo signal is estimated according to the different rotation speed of UAV rotor, and then, according to the estimated period, echo signal subsection superposition method is adopted to separate the echo signal of each UAV, realizing only one observation signal, accurate separation of echo signals of each target in the UAV group composed of10 UAVs.
