Problems solved by technology
[0003] 1. The current monitoring range is single, and the equipment can only monitor a single frequency band, which cannot meet the task requirements in a complex multi-task environment
[0004] 2. The real-time performance is not high, mainly because the interference analysis requires professional technical support, and the complex interference analysis process is difficult to meet the operational needs in real-time
[0005] 3. The automation level of the perception system is low, and the organic combination of monitoring, intelligent analysis and monitoring reports cannot be realized
[0006] 4. The equipment is bulky and inconvenient to carry and operate in the field

The invention discloses a designing method for a radio spectrum sensing technology, which relates to a spectrum analysis automation technology in the field of radio measurement and control. The method is implemented by a bandwidth antenna, a spectrum monitor and a data analysis computer. In the method, a portable broadband antenna designing way is adopted, data acquired by the portable spectrum monitor is processed and analyzed by the data analysis computer, and analysis results automatically show recommended application work channels. The method has the advantages of wide frequency coverage range, small volume, light weight, portability, convenience and the like, and can be widely applied in the fields of aerospace measurement and control and unmanned aerial vehicle measurement and control and to the modern complex electromagnetic environment battlefields.
Description
technical field [0001] The invention relates to an automatic frequency spectrum analysis technology in the field of radio measurement and control, and is especially suitable for aerospace measurement and control, unmanned aerial vehicle measurement and control, and modern radio measurement and control complex electromagnetic environment battlefields. Background technique [0002] At present, the diversification of weapons and equipment, the coordinated operations of multiple arms, the intensive distribution of frequency resources, whether the system can operate in a complex electromagnetic environment, and how to avoid interference have put the development of radio monitoring technology on the agenda. The current monitoring capability needs to be improved for the following reasons: [0003] 1. The current monitoring range is single, and the equipment can only monitor a single frequency band, which cannot meet the task requirements in a complex multi-task environment. [000...
