Abstract :
Based on the translational characteristics, attitude motion and electromagnetic scattering characteristics of the midcourse warhead, a high-precision approach for wideband echo simulation of the midcourse warhead target is put forward in this paper. This approach firstly carries out translational modulation of the warhead target through the geometric model between radar and the warhead target, then maps the three-dimensional attitude motion characteristics of the warhead target on the radar observation plane, so as to obtain the instant aspect angle between the radar sight line and the symmetry axis of warhead target, subsequently extracts the complex scattered field data of omnidirectional warhead target obtained through electromagnetic calculation according to the instant aspect angle, thereby obtaining the wideband radar echo simulation result of the micro motion of the midcourse warhead target, and finally, validates the effectiveness of this approach based on the simulation data processing result of midcourse warhead in high performance computers.
