The plasma sheath covering the vehicle’s surface will be generated during the reentry of the hypersonic vehicle， which has a complex modulation effect on the electromagnetic （EM） wave and significantly affects the scattering characteristics of the hypersonic vehicle. This paper analyzes the bistatic polarization scattering characteristics of a plasma-sheath-covered hypersonic vehicle. Based on the plasma sheath parameters at typical heights and velocities solved by numerical simulation， the current density convolution method was used to simulate the interaction between the linearly polarized plane EM wave and the hypersonic vehicle. The bistatic scattering components （co-polarization and cross-polarization） at the pitch angles of -90°-90° are obtained by the far-field extrapolation method. Through studying the direction distribution characteristics of polarization scattering under different conditions of flight and incident wave at typical radar operating frequency points， this paper analyzes the effects of flight height， incident angle and polarization mode on the bistatic polarization RCS of the plasma-sheath-covered blunt cone.
