摘要
测定了箔条弹在距地面３ｍ高度上抛撒的箔条云对８ｍｍ波的衰减曲线。每发弹生成了独立的箔条云。由于箔条云的均匀性和掩护范围受气流影响，只有箔条云进入到８ｍｍ波接收机的波束角，才能产生明显的衰减效果。箔条云的扩展范围随时间变化。箔条云的有效反射面积与实测衰减曲线进行了比较。指出在近地面高度抛撒箔条云是干扰８ｍｍ波的有效技术途径。
Attenuation curve of the chaff cloud that is spread by a chaff bomb at a distance of 3 m above the sarface of ground for an 8 mm wave is measureEach chaff bombproduces its own independent chaff cloud.Since the uniformity and the covering scope ofthe chaff cloud are affected by airflow,significant attenuation effect can be produced onlywhen the chaff cloud comes into the wave beam angle of an 8 mm wave receiver。 Thespreading scope of the chaff cloud varies with time,A comparison is made between the ideal value of the effective reflection area and the experimental attenuation curve。It showsthat to spread the chaff cloud near the surface of ground is a useful approach to interferean 8 mm wave。
