Paper Abstract

In this paper, we simulate cylindrical and conical aircraft’s Doppler spectra caused by its spin. The characteristics of Doppler shift spectra and backscattered power are analyzed when the reflectance of aircraft surface material is Lambert and exponential terms. The results show that the Doppler frequency shift is doubled as well as the radius is doubled with the same height. When the radius remains unchanged and the height increases, the backscattered power increases. Compared with the Lambertian case, the backscattered power in the exponential case decreases faster with the Doppler shift from the peak and increases faster with time. These findings results can be used to detect flying targets in space.
