Aircraft external radio frequency electromagnetic environment prediction method and prediction system

Abstract

The invention relates to the technical field of electromagnetic environment prediction, and discloses an aircraft external radio frequency electromagnetic environment prediction method and a prediction system. The system comprises an electromagnetic environmental parameter acquisition device, a data center, a simulating calculation center and a visual output terminal device. The method is that collected electromagnetic environmental parameter information of radiation sources, atmospheric environment, ground environment and sea environment is transmitted to the data center which is connected through networks by means of the electromagnetic environmental parameter acquisition device, and is stored in a data base which corresponds to the data center. The data center is connected with the simulating calculation center through a data line, and the simulating calculation center enables comprehensively predicted data model information of aircraft external radio frequency electromagnetic environment to be transmitted to the visual output terminal device which is connected through a video bus, so that the electromagnetic environment can be displayed comprehensively. According to the aircraft external radio frequency electromagnetic environment prediction method and the prediction system, an improved signal description word method is adopted to conduct modeling of aircraft external electromagnetic signal environment, and therefore the signal processing operational amount is reduced and the prediction efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of electromagnetic environment prediction, in particular to a method and system for predicting the radio frequency electromagnetic environment outside an aircraft. Background technique [0002] The electromagnetic environment refers to the sum of all electromagnetic phenomena existing in a given place or space. Complex electromagnetic environment refers to the electromagnetic environment in which various electromagnetic signals are dense and overlapping in a certain frequency band in a limited time and space, which hinders the normal operation of information systems and electronic equipment and has a significant impact on information systems and electronic equipment. It is a complex electromagnetic environment. representations in the space, time, frequency, and energy domains. [0003] Judging from the existing research situation, the current electromagnetic environment prediction methods cannot meet the re...
