Abstract

The invention discloses a method for quickly predicting frequency-point mutual interference of electronic equipment. The method comprises the following steps: step 1, performing interference pre-judgment on a large number of electronic equipment, and preliminarily screening out pairs of transceiver equipment that may interfere; step 2, passing The interference prediction algorithm performs accurate frequency point-level interference prediction on the equipment pairs at the screening place, generates an interference matrix, and assists in formulating a frequency point allocation plan based on the interference matrix. It can quickly predict the frequency point mutual interference of electronic equipment that contains a large number of operating frequency points. This method is suitable for narrowband pulse signals and wideband continuous wave signals. data support. The principle of the method of the invention is concise and clear, and the engineering practicability is strong.

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...
