What is the Electromagnetic Spectrum?

The electromagnetic spectrum refers to a family of electromagnetic waves arranged continuously in accordance with the wavelength (or frequency) of the electromagnetic waves. In the military, the electromagnetic spectrum is not only a carrier for transmitting information, but also an important means of reconnaissance of the enemy. Therefore, it has become one of the commanding heights of both sides in the war.

Electromagnetic spectrum-a magical invisible world. With the rapid development of the army's informatization construction, it has become an important weight influencing the outcome of war on the battlefield in the future.

Electromagnetic spectrum management

The electromagnetic spectrum is

Electromagnetic spectrum is a limited resource. With the rapid development of traditional wireless services and emerging wireless services, limited electromagnetic spectrum resources will eventually be exhausted. The contradiction between electromagnetic spectrum requirements and electromagnetic spectrum resources is increasingly prominent. The safe use of the electromagnetic spectrum presents serious challenges.

Traditional wireless services such as

Spectrum is a limited, non-renewable strategic resource. As a country's public resources, except for a part allocated to the military, most of it is shared by the military and civilians. Therefore, all countries attach great importance to cherish and make full use of it. In the military field, the future battlefield is characterized by a large number of equipment, full types, large radio density, complex programs, and rapid changes in the electromagnetic environment. If the spectrum management is not strengthened, it will inevitably cause problems such as communication interference and poor communication, which will affect the whole Success or failure of the battle. According to foreign newspaper reports, during the Gulf War, the wireless networks managed by radio frequencies were more than 7,500 high-frequency networks, more than 1,200 VHF networks, and 7,000 UHF networks. These all indicate from different aspects that without orderly electromagnetic spectrum management as the basis, information operations will be greatly restricted and affected. Therefore, we must have a sober understanding of electromagnetic spectrum management. We must actively track the development frontier of the world's military spectrum management, conduct in-depth research, and constantly strengthen supervision. Its focus is to strengthen the establishment of military-ground electromagnetic spectrum co-management, co-construction, and sharing mechanisms, build a platform for resource sharing, do a good job of the three armed forces, effectively promote the process of military-ground resource sharing, and change from a single technical support to multidimensional omnidirectional management.

Some military powers in the world generally believe that the electromagnetic spectrum is the only important media that can support mobile operations, decentralized operations, and high-intensity operations. Foreign troops commented that "spectrum is a form of intangible combat power and a new type of combat power comparable to firepower and mechanical power." It even predicted that "the 21st century will be an era of spectrum warfare"; "wartime frequency resources are like ammunition and oil Equally important is the necessary material foundation for combat. "Therefore, to strengthen information construction and strengthen spectrum management, together with the overall enhancement of combat effectiveness, and the victory of future information warfare, we must attach great importance to it. ^[2]
