Points to Note
news background long ago, our military held a “Beyond 2009″ series of exercises cross real soldiers, the scale of travel away, the equipment of the essence, the first time in our military history. The media have coverage, the news is often a “complex electromagnetic environment of communication anti-jamming capability” is used. So, what is a complex electromagnetic environment? Electromagnetic interference with communication complexity of the environment and the future of information operations What is the relationship? With these questions, we interviewed a deliberately anti-jamming communications expert Yao Fuqiang researcher.
Yaofu Jiang, Ph.D., a researcher and PhD supervisor, the General Staff is currently a director of the Institute, enjoy special government allowances, excellent professional and technical personnel by military award, the army signal corps of military theory the direction of special anti-jamming communications appointed chief researcher, Jiangsu Province, young chief scientist. Completed several countries, the key military communications projects, many times by the National Science and Technology Progress Award, the military and technological progress award and national invention patents, published 2 monographs, and published more than 200, three times awarded the second class .

– Interview with the General Staff of a researcher, communication interference expert Yao Fuqiang
■ Chen Feiqiong
asked: “Beyond 2009″ phone-dispersed, as anti-jamming communications experts in the field, how do you see the exercise it?
Yaofu Qiang: I think, “Beyond 2009″ is a similar information under the conditions of global warfare exercises covering the long-range mobility, ability to obtain intelligence, command and control, situational awareness, fire strike capability and integrated support capabilities and other fields. We see images on television is its major physical side, and its invisible side also go hand in hand, it is a complex electromagnetic environment of combat capability.
Q: How to understand the commonly referred to as “complex electromagnetic environment”?
Yao Fuqiang: complex electromagnetic environment is defined as a certain spatial, temporal, frequency and power domains, multiple electromagnetic signals exist, the use of weapons and combat operations have a certain affect the electromagnetic environment. A quantitative basis, the complex electromagnetic environment is divided into several levels. Elements of a complex electromagnetic environment there are many, such as: human intention electromagnetic interference, electromagnetic interference of human intention, industrial disturbance, and natural disturbances. Data shows that the deployment of a division within an area of ??3000 square kilometers in only up to 3000 radio stations on the remnants of an army with as many as ten thousand on, together with other military and electronic equipment, electromagnetic radiation, there is an enemy in wartime party interference, showing the formation of the modern battlefield electromagnetic environment is quite complex.
Q: Faced with the complex electromagnetic environment, how important is communication interference in the end?
Yao Fuqiang: the core of future information warfare is information superiority, we must first ensure the smooth flow of information, especially in the face of complex electromagnetic environment of electronic attack on the enemy, no doubt from the anti-jamming communications a “shield” role, to protect communications between the command and weapons uninterrupted transmission of information, or to reduce interference. Visible, communications interference is not only to protect communications, and given the defensive operations of the function, which is different from the civilian military communications traffic is an important symbol, reflects the army’s combat power has become a new playing field and the development of cutting-edge weapons research . In the late 20th century, several modern local wars, especially the Kosovo war and the Iraq war, all that a truth, who does not attach importance to the electromagnetic space of struggle, who will lose the initiative in war.
Q: communication anti-jamming is the first in war time?
Yao Fuqiang: communication interference can be traced back the history of World War I, typical of the wars of 1914 Britain and Germany launched a naval battle in the Mediterranean in the electronic communications combat operations, Dejian launched with the British warship HMS same radio frequency noise, the British side has repeatedly attempted to avoid artificial changes in communication frequency interference, pulled from the history of human interference and anti-jamming communications prelude. To the 1991 Gulf War, the use of electronic warfare has reached an unprecedented scale and level of degree, course and outcome of the war had a significant impact, national army interference from the communication’s role in modern warfare has become more clear position understanding.
Q: The international anti-jamming technology on the level of communication?
Yao Fuqiang: in a “fight” after a long period of time, some countries used to manually change the frequency of major or artificial means to increase the power of such interference. Later, the gradual emergence of anti-jamming technology tools, especially the last century, 60 to 70 years after the emergence of spread-spectrum communication theory, combined with new technologies, new device applications, communications jamming technology and equipment began to be developed and applied. Today, many military power has been achieved in time domain, frequency domain, airspace, power domain, speed, domain, network domain such as multi-dimensional space of communication interference, their equipment has covered all the tactical, operational and strategic radio communications, even Some platforms are equipped with communication anti-jamming capability. According to reports, the current international anti-interference ability of U.S. military equipment is protected satellite communications systems, such as: “Military Star (MILSTAR) System”, “Advanced Extremely High Frequency (AEHF) satellite communications system”.
Q: Can you briefly explain the development of military communications interference situation?
Yao Fuqiang: military communications interference experienced a scratch, the process of gradual improvement, although the late start, but rapid development. Technology and equipment from the building, first began in the early 1980s, after decades of hard work, self-development, anti-jamming communications equipment now covered the main military communication bands, various means, formed its own characteristics , and further deepen the communication of electronic defense systems to build. Construction and personnel training in the discipline, the army has established the direction of the appropriate professional research center, doctoral and master’s degree and post-doctoral research station, regularly held for the troops’ use of training courses organized communication interference, “to form a more perfect communication interference disciplinary system and personnel training system.
Q: With some of the new anti-jamming communications equipment in succession with the troops, you have to use these primary forces in the process of new equipment have any suggestions?
Yao Fuqiang: There is a misunderstanding, some people think that military interference with the communication of new equipment, it means improved communication anti-jamming capability. In actual fact, at least two prerequisites, one communications system to unify the development of anti-interference technology, or prone to single-loaded anti-jamming capacity, but the collaborative exchange capability is reduced, which under the condition of the armies and information contrary to the needs of combined operations in many countries in it have a profound lesson. Of course, this is the top-level design issues. Second, the requirement for unified communications interference parameters control the battlefield, especially in frequency hopping communications equipment even more so. Many foreign armies, the painful lessons of the war that: If there is no uniform hopping parameters control the battlefield, there will be you jump, I jump, everyone is jumping, the final total chaos, not the exchange of communication, not through the exchange of chaos and serious mutual interference, anti-jamming capability and network efficiency is greatly reduced. This is the top-level design issues, is the organization to use the issue.
Q: Please explain further the development of future prospects of communication jamming technology.
Yao Fuqiang: If electromagnetic interference as a “spear”, that immunity is the “shield.” In fact, there is no all-conquering spear, nor shield can not be overcome, as long as the threat of war exists in the world, then the interference of electromagnetic interference and will not be endless, and will continue to develop in the war, is a “magic goes, Road ridge “, which is an eternal subject of army building. In the next period of time, in response to electromagnetic interference and electronic surveillance technology has brought the threat, the need to develop multi-dimensional space of generalized interference, establish and improve communication electronic defense systems, focusing on the dynamic anti-interference, anti-interference technology, smart, improve the multi-layer anti-jamming electronic defense and intelligence level. Meanwhile, anti-jamming communications to the gradual resolution of the conflict with the required bandwidth. In addition, now we talk about communication and more generally refers to wireless interference, but the wired communications interference problems worth studying.
