A Parameter Extraction Method Based on Anti Rotor Unmanned Aerial Vehicle

Vortex electromagnetic wave radar can obtain more accurate rotation parameters of rotor targets for the classification and recognition of unmanned aerial vehicles. However, existing parameter extraction algorithms make it difficult to obtain variable velocity motion information about targets under oblique incidence conditions. Based on this, this article proposes a parameter extraction algorithm that can be applied to variable-speed moving targets. The Doppler effect of accelerating moving targets under oblique incidence conditions is studied, and the parameters of target acceleration, tilt angle, rotation radius, etc. are successfully extracted. The simulation results have verified the effectiveness of the proposed algorithm.
