一、干扰的分类按产生的原因,可分为自然干扰和人为干扰。自然干扰是指大自然产生的干扰(雷电、雨、雪等);人为干扰是指由辐射电磁波的装置产生的干扰。人为干扰按其产生的方法,还可分为有源干扰和无源干扰。有源干扰由专门的无线电发射机产生;而无源干扰,则由各种物体反射电子设备发射的电磁波形成。有源干扰按其作用效果,又可分为压制式干扰和欺骗式回答干扰。压制式干扰:在宽频带内辐射类似噪声信号,使接收机难以
First, the classification of interference by the causes, can be divided into natural and man-made interference. Natural disturbance refers to the interference caused by nature (lightning, rain, snow, etc.); Human disturbance refers to the interference caused by the device radiating electromagnetic waves. Man-made interference generated by the method can be divided into active interference and passive interference. Active interference is generated by a dedicated radio transmitter; passive interference is caused by electromagnetic waves emitted by various objects reflecting electronic equipment. Active interference by its effect, but also can be divided into repressive interference and deceptive reply interference. Suppressed interference: radiating a similar noise signal over a wide frequency band, making the receiver difficult
