Abstract�� Appropriate coating material can reduce the back radar cross scatter of air target, at the same time, it may affect the glint of target greatly. To study this affection, first, through physical optics and impedance boundary condition the radar cross section(RCS)was obtained in graphic electromagnetic computing (GRECO) in high frequency region, then using phase gradient method, the glint model of coated target was created. Due to the characters of graphic electromagnetic computation, the computation of glint of coated target has visual, rapid and efficient features. On the basis of this visual method the computation was performed on one two-sphere target and one complex target, respectively. The results show that the coating material can not only reduce radar cross section but also enhance the glint certainly.
