An Accurate Technique for Extended Target Radar Echo Simulation Based on the Scattering Center Model

In this paper, a radar echo simulation technology based on the scattering center model is proposed to achieve precise simulation of extended target radar echoes. By introducing a LFM signal that conforms to the radar working mechanism, the simulation accuracy of the echo signal has been improved. Compared with existing algorithms, the proposed method uses a scattering center model based on geometric diffraction theory, achieving a balance between accuracy and efficiency. The effectiveness of the proposed method is verified by the simulation results.
