A Rapid Discovery Method of Radio Radiation Sources Based on Simulation Space Dynamic Search

Abstract

The method is suitable for the field of communication simulation countermeasure, and provides a radio radiation source fast finding method based on simulation space dynamic searching. All the red-square radio radiation sources in the simulation space and the signal characteristics of all the red-square radio radiation sources in the simulation space are obtained through traversing, firstly, signalcharacteristic pre-screening is carried out, and a radiation source which can be found can be extracted, and then the Fresnel distance is calculated to determine a propagation loss model, and the signal power intensity received by the detector from the radiation source is calculated on the basis, and a complex electromagnetic field intensity coefficient is superimposed, so that when the number ofthe radiation sources in the simulation space is large, the detected radio radiation sources can be quickly searched and found, and the characteristic information of the radio radiation sources can be extracted, and the timeliness of the simulation operation of the simulated training of the command information system is improved.

Description

technical field [0001] The invention belongs to the technical field of communication simulation countermeasures, in particular to a method for quickly discovering radio radiation sources based on dynamic search in simulation space. Background technique [0002] During the implementation of communication countermeasures in the simulated training of the command information system, the real-time dynamic discovery of the radio radiation source of the red party in the simulation space is the prerequisite for the blue party's training system to carry out communication electronic warfare strikes. The radio radiation source on the other side will take too long and occupy a large amount of computer resources, resulting in data loss within the current simulation time, and the simulation operation cannot be carried forward normally. [0003] The existing scheme is: after a series of data preprocessing on the communication signal of the radio radiation source obtained by the receiver, B...
