Abstract :
The impact of barchan shape on the radar cross section is addressed in this paper. Firstly, a barchan model is introduced with the wind-blown theory and shapes of barchan models with different cycle times are compared. Then, radar cross sections are calculated by the discrete element method which bases on Kirchhoff Approximation. Monostatic and bistatic cross sections are compared and analysed when electromagnetic wave is incident to two side faces, up-wind face and lee face, respectively. Finally, the influence of barchan shape on radar cross sections is discussed.
