RCS 2D-imaging of Rotating Targets

In this paper, RCS 2D-imaging of rotating targets is analyzed using Kirchhoff integral theorem. It is shown that the imaging section includes the axle from radar stage to rotating stage and the imaging section is vertical to the line connecting two antennas. That is, when the line and the imaging section are coplanar, only a RCS 1D-imaging of rotating targets can be obtained, and when the line is vertical to the imaging section, a RCS 2D-imaging of rotating targets can be gotten. The results obtained in this paper give a theory base for the system design of RCS 2D-imaging of rotating targets.
