最基本的电子干扰(ECM)仍然是噪声干扰(noise jamming)和主要用于对付搜索与跟踪雷达的欺骗干扰(deception jamming),欺骗干扰常使用到数字射频存储器(DRFM)。为了干扰已采取了抗干扰技术措施的雷达、通信等发射机,如频率捷变、跳频和扩谱等宽带发射波形,噪声干扰已从瞄准式(spot)发展到宽带阻塞式(broad-band barrage)和转发式(repeat)干扰方式。 最近外刊反映,现代ECM系统采用“详查”(look-through)噪声干扰方式。它克服了以前的噪声干扰存在的以下不足:(1)噪声干扰机在实施干扰时或实施干扰后,几乎不了解干扰效果如何,即对方辐射源被干扰的特性变化;(2)不加区别的使用噪声干扰机很浪费干扰资源;(3)会危及干扰平台的安全,因为任何干扰辐射源都很容易被测向设备测出,从而成为反辐射导弹的攻击目标,反过来如果不辐射,干扰发射也就无意义了;(4)为了解决此问题,绝大多数
The most basic types of electronic interference (ECM) are still noise jamming and deception jamming primarily for search and tracking radars, which are often used in digital radio frequency memories (DRFMs). In order to interfere with the radar, communication and other transmitters that have adopted the anti-interference technical measures, such as wideband transmit waveforms such as frequency agility, frequency hopping and spectrum spreading, the noise interference has progressed from a spot to a broad-band barrage and repeat interference. Recent external publications reflect that modern ECM systems use “look-through” noise interference. It overcomes the following shortcomings of previous noise interference: (1) The noise jamming machine has little or no understanding of the interference effect when the jamming is implemented or after the jamming is performed, that is, the change of the characteristic of the jamming of the other party’s radioactive source; (2) (3) It will endanger the security of the interference platform because any sources of interfering radiation can easily be detected by the equipment to be measured, thus becoming the target of anti-radiation missiles. In turn, if the radiation is not radiated, Interference emissions also meaningless; (4) In order to solve this problem, the vast majority
