Rapid prediction method for frequency point mutual interference of electronic equipment

Abstract

The invention discloses a rapid prediction method for frequency point mutual interference of electronic equipment. The method comprises the following steps of: 1, carrying out interference pre-judgment on a large amount of electronic equipment to preliminarily screen out a transceiver equipment pair which generates interference possibly; and 2, performing accurate frequency point-level interference prediction on the screened equipment pair through an interference prediction algorithm, generating an interference matrix, and assisting in establishing a frequency point distribution scheme according to the interference matrix. Rapid prediction can be carried out on the frequency point mutual interference of the electronic equipment with a large number of working frequency points; and the method is suitable for narrow-band pulse signals and broadband continuous wave signals, can be applied to the prediction of interference between the frequency points of the electronic equipment, and provides data support for spectrum planning of the electronic equipment. The method is concise and clear in principle and high in engineering practicability.

Description

technical field [0001] The invention relates to the field of electromagnetic interference prediction, in particular to a fast prediction method for frequency point mutual interference of electronic equipment. Background technique [0002] Electromagnetic spectrum resources are becoming increasingly scarce. For areas where a large number of electronic devices are distributed, interference prediction between electronic devices and spectrum resource allocation are key issues. The electromagnetic spectrum interference of electronic equipment is not only the main frequency interference of frequency-using equipment, but also the sideband, harmonic clutter, and intermodulation and intermodulation interference of frequency-using equipment. The electromagnetic spectrum of electronic equipment in an area usually occupies a certain spectrum width. The more types and quantities of high-power electronic equipment and the wider the spectrum occupation, the more serious the electromagnetic...
