箔条一种由金属箔、金属丝或涂覆金属的介质制成用以对敌方雷达实施无源干扰的器材。通常有干扰丝、干扰片、干扰带（绳）等。其长度通常约为被干扰雷达波长的一半，主要是通过对雷达发射的电磁波谐振而产生强烈反射来实施干扰，所以亦称偶极子反射体。干扰箔片、带多采用延展性好、比重轻的铝箔制成,厚度一般为8～25微米。干扰丝多用玻璃纤维、尼龙丝作基体，表面涂覆铝、锌、银等金属，直径在十几至几百微米之间，其中常用的为25微米。为便于使用和储存，一般将箔条包装成束、卷、包，组合成捆。使用时，由装在飞机、军舰或地面上的投放（发射）装置投射到空中，在气流的作用下散开形成箔条云。箔条的战术使用主要有以下几种：①在空中大面积连续投放，形成干扰走廊或干扰屏障，以掩护己方机群的作战行动。②间断投放有效反射面与真目标相近的箔条包，形成许多雷达假目标，造成敌方雷达操作人员判读困难及数据处理系统过载。③飞机、军舰在受到敌方雷达跟踪时，投放能迅速散开的箔条包或发射速爆箔条弹，形成雷达诱饵，以摆脱敌方雷达的跟踪。箔条造价低廉，使用方便，易获得宽频段特性，能同时干扰不同方向、不同频率、不同体制的多部雷达。但对脉冲多普勒及动目标显示等具有速度处理能力的雷达，干扰效果较差。同时，易受当时气象因素的影响。
