【摘要】 用矢量微扰动理论一阶解分析减小目标后向散射系数的方法。表明降低表面粗糙度并采用大块面外形结构以增大可能的入射角可大大降低回波强度；在目标表面形成取向性的条纹状起伏时，散射分布也具有取向性，这种方法可以高效率地产生激光隐身效果；尽量减小目标的奇数次后向散射，可以有效地回避相干激光雷达的探测。主要结论都作了实验验证。更多还原

【Abstract】 The first order solution of the vector small purturbation theory is developed to analyse the methods of reducing the backscattered intensity. It shows that weak roughness on big plates or one dimensional surface roughness produce concealment effect for laser radar detection. For coherent laser radar case, the conclusion is drawn that it will greatly decrease the backscatterring to keep rotation of the scattered light doesn’t reverse when targets are illuminated by ellipse polarized beams. All dominant point of views are demonstrated by experiments.更多还原
