| 摘 要： | 对目标表面强散射区涂敷雷达吸波材料（radar absorbing material, RAM）是雷达散射截面（radar cross section, RCS）减缩的有效方法。基于射线追踪法（shooting and bouncing rays, SBR）提出一种确定复杂目标强散射区的方法：根据射线管出射方向与雷达接收方向的夹角判断强散射区。分析了复杂目标强散射区涂敷RAM的RCS减缩特性，并研究了判断夹角取不同值时强散射区大小和涂覆RAM后的减缩效果。计算结果显示，对强散射区涂覆RAM可以在重量增加不大的情况下有效降低目标RCS值。

| Abstract: | Coating the strong scattering region of target surface with radar absorbing material(RAM) is one of the effective methods for radar cross section(RCS) reduction.A definition of strong scattering regions based on shooting and bouncing rays(SBR) is given: judging a strong scattering region based on the included angle between outgoing direction of rays and receiving direction of radar.The RCS reduction characteristic of complex target's strong scattering region coating RAM is analyzed,and the size of the stron... |
