摘　　要：为选择适合作为激光诱偏假目标的自然地物以获得更好的诱偏干扰效果,实际测量分析了几种典型自然地物的激光反射系数,如草地、土地及卵石地面等,并讨论了反射能量与反射角的关系,分两种情况分析示意了照射激光和干扰激光的反射能量空域分布。实验及分析结果表明,在其他状态一定的前提下,选取草皮、土壤覆盖的草坡、土坡等自然地物设置为激光诱偏假目标的诱偏干扰效果更好。最后对自然地物激光诱偏假目标设置时的材料及面形选择提出了建议:应尽量选择假目标面法线与激光制导武器导引头视场光轴趋于一致的草坡或土坡。For sake of selecting suitable natural object for laser decoy false target to get better decoy interference effect,the laser reflectance of some typical natural objects,such as grass,land and pebbles ground,etc,and connection of the reflected energy and angle was analyzed in actual measurement,the spatial distribution of reflected energy of irradiation laser and jamming laser both was analysed and drawed.The results of experiments and analysis show that on the premise of same condition,selecting glass slopes,earth slopes and other natural objects covered by turf or soil for laser decoy target can attain better decoy interference effect.Finally,selection of the material and shape of natural objects for laser decoy false target was recommended： try to select glass slopes or earth slopes as false target which face normal is close to the optic axis of laser guided weapon seeker′s field of view.
