导弹、飞机、军舰和坦克要靠伪装来防止被雷达探测是相当困难的。但只需在物体上涂覆吸波材料或采用能减弱散射的结构形状便可降低被探测的概率,因此,只有不断减少物体的雷达散射截面才能获得明显的效果。散射截面减少一半,目标探测距离缩短1/16,因为 Missiles, airplanes, warships and tanks rely on disguise to prevent radar detection is quite difficult. However, the probability of being detected can be reduced by simply coating the object with the absorbing material or by using a structure that reduces the scattering, so that only significant reduction of the radar cross section of the object can be obtained. Scattering cross-section by half, the target detection range shortened by 1/16, because
