为了生成在物理域中真实有效的对抗样本,在可见光领域,相关研究人员通过在目标物体上添加贴纸[19,20]、补丁[21]、服装[22,23]、图像[24,25],或通过改变场景中的光照[26,27]、天气[28−30]、相机参数[31,32],以及使用化妆[33]、3D打印伪影[34,35]等形式来改变目标光学成像的反射特性,从而破坏检测模型识别...
2.2 System model In the case of 3D SAR, the reflectivity of a scene, which may consist of one or more targets, is determined by analysing the echoes collected coherently at a series of spatial positions. To gather the reflectivity of a scene within the transmitter's field of view, the ra...
