Simulation Of Bistatic Signatures From Rotating Blades Of Aerial Targets

The proper design of aerial target classification algorithms includes debugging, adaptation, and validation stages that require a large number of experimental or simulation data. Obtaining real radar data is usually time-consuming and in some cases requires relatively high costs. The use of mathematical models representing the realistic signature can significantly reduce such expenses. This paper describes the mathematical model representing the signal reflected from rotating blades of propeller-driven aerial targets in the bistatic radar. The spectrum signatures of the helicopter rotating blades are simulated for different bistatic angles. The simulation results of the spectrum of the signal reflected from the multi-rotor drone under different bistatic angles are compared with the measured data.
