With the rapid development of modern communication technology, electronic interference has become more and more complex and widespread. Jamming has become a very effective weapon for hostile forces. Especially for the military, the frequency of radio spectrum interference is becoming more and more frequent, which means that the interference countermeasure technology of RCIED needs to be deeply studied. There is no doubt that jamming countermeasure technology will be the most important part of future war, so this paper will discuss the research of RCIED jamming countermeasure technology from the following aspects.
Overview of RCIED jamming countermeasures
RCIED stands for remote control explosive device, which is a very dangerous weapon. RCIED can be used in a variety of hostile activities, including terrorist attacks, war, and more. An RCIED is an electronic device that is usually detonated remotely by the manufacturer or controlled using a radio wave receiver. Once the remote receiver is found, jamming measures can be taken to protect themselves and the people.
Interference countermeasure technology, popular point is the pointer to RCIED electronic interference measures. At present, we can prevent RCIED from the following aspects:
(1) Transmitted signal interference: Transmitted interference signals can offset the RCIED operator's radio signals.
(2) Electromagnetic shielding technology: protect yourself by shielding your own equipment to prevent the transmission of interference signals.
(3) Electromagnetic frequency scanning: By scanning the preset frequency range, find the signal source of RCIED, and then further interfere with it.
The transmitted signal interference of jamming countermeasure technology
The transmitted signal jamming technique is one of the most common techniques used to counter RCIED. This technique is designed to interfere with the proper working and operation of the RCIED by transmitting interference signals to it. This technique includes a variety of characteristics, including the strength of the interference signal, the frequency of the interference signal, and the modulation of the interference signal.
However, the strength of the interference signal also needs to be controlled. If the strength of the interference signal is too large, it may affect the normal work of other equipment around, and cause other adverse effects. Therefore, the strength of the interference signal should be determined according to the needs and the principles of the use of the environment, and the strength can not be increased at will.
The frequency of the interference signal is another factor to consider. Generally speaking, the operating frequency of RCIED is relatively fixed, so we should set the emission frequency for the electromagnetic belt near the frequency, in order to interfere with the normal operation of RCIED as much as possible.
In addition, the modulation of interference signals is also a point that needs attention. Modulation techniques are designed to make the jamming signal look more like the RCIED operator's normal signal, thereby avoiding being aware of the presence of interference.
Electromagnetic shielding technique
Electromagnetic shielding technology is another scheme used in interference countermeasure technology. The technology is designed to protect one's own equipment by using electronics to isolate radio signals from RCIED. This technique is more suitable for situations that require high confidentiality, such as government agencies or military bases.
The key to this technology is the use of electromagnetic plates, which isolate electromagnetic waves around the device, but can affect the performance and function of the device. Therefore, when using this technology, it is necessary to weigh the shielding effect and the functional performance of the device.
Electromagnetic frequency scanning
Electromagnetic frequency scanning technology is also a common interference countermeasure technology. The technology is designed to find the source of an RCIED operator's signal by scanning its frequency range. Once the source of the signal is found, attempts can be made to counter the RCIED by transmitting a jamming signal.
This technology is relatively efficient, and there is no condition to make electromagnetic shielding, more practical, but also more recommended.
Sum up
RCIED interference countermeasure technology is an important technical means to prevent RCIED. At present, the interference countermeasure technology for RCIED mainly includes transmitted signal interference technology, electromagnetic shielding technology and electromagnetic frequency scanning technology. All of these technologies allow users to avoid or mitigate RCIED interference.
