【摘要】：眾所周知,信息戰(zhàn)已經(jīng)成為現(xiàn)代戰(zhàn)爭中的主要組成部分,怎樣才能掌握戰(zhàn)場中的“制信息權(quán)”成為軍事通信領(lǐng)域主要研究對象。戰(zhàn)場形勢日趨復(fù)雜,各種軍事通信高技術(shù)相繼成熟化,對信息的爭奪也更加激烈�，F(xiàn)代戰(zhàn)爭是信息化條件下陸、海、空、天一體化的聯(lián)合作戰(zhàn),高效可靠的軍事通信是贏得戰(zhàn)爭勝利的關(guān)鍵因素之一。敵方針對軍事無線通信的干擾手段和干擾樣式也在不斷發(fā)展。為了抵抗這些不斷變化的干擾,各種各樣的抗干擾手段應(yīng)運而生,各種擴頻的、非擴頻的,時域的、頻域的、功率域的抗干擾技術(shù)與措施由于它們的抗干擾機理不同,因此可以抵抗不同的干擾信號,但由于敵干擾手段的不斷變化,其干擾形式正由固定干擾向動態(tài)干擾、由壓制干擾向靈巧干擾發(fā)展,其中動態(tài)干擾樣式對軍事無線通信威脅更大,也對通信抗干擾提出了新挑戰(zhàn),而傳統(tǒng)的干擾方式多是通過改變發(fā)送信號的某些特征來進(jìn)行抗干擾,如果可以了解干擾信號的某些參數(shù)特征,針對這些特征來避免干擾,這將是一種非常行之有效的抗干擾方法。目前敵方干擾形式多種多樣,針對不同的干擾具有不同的抗干擾手段,針對這些抗干擾手段許多學(xué)者也進(jìn)行了仿真分析研究,但這些仿真分析都是獨立進(jìn)行,對于使用者來說難于進(jìn)行不同抗干擾方式效果的比較,難于對抗干擾仿真效果進(jìn)行比較,因此,如果能夠?qū)@些干擾手段、提取的參數(shù)準(zhǔn)確度以及抗干擾的效果進(jìn)行綜合分析,開發(fā)出能夠綜合各種仿真的抗干擾仿真實驗平臺將具有重要的實際意義。首先,本文簡要分析了課題研究的背景、目的和意義,討論了抗干擾仿真實驗平臺開發(fā)的主要內(nèi)容以及研究的思路和方法。其次,本文針對抗干擾仿真平臺開發(fā)的需求,分析了干擾信號模型及其數(shù)學(xué)表達(dá)方式,分析了干擾信號特征參數(shù)提取的主要算法以及通信抗干擾技術(shù)的原理、抗干擾常用算法和相關(guān)的難題,為仿真平臺的開發(fā)提供理論基礎(chǔ)。再次,在介紹Matlab仿真軟件的基礎(chǔ)上,對通信抗干擾仿真平臺的需求進(jìn)行總結(jié)分析,給出軟件的基本結(jié)構(gòu)及需要設(shè)計的主要內(nèi)容和對象,自主編寫了通信仿真的基本程序以及干擾信號和抗干擾算法的程序,并對各仿真程序進(jìn)行了調(diào)試與測試,開發(fā)了仿真平臺界面,并利用該平臺給出了抗干擾的仿真結(jié)果,對結(jié)果進(jìn)行了分析。最后,本文對全文的工作進(jìn)行了總結(jié)分析,指出了需進(jìn)一步研究的問題。
[Abstract]:As we all know, information warfare has become the main component of modern warfare. How to master the "power of information" in the battlefield has become the main research object in the field of military communication. The battlefield situation is becoming more and more complex, various military communications high-tech has matured, and the competition for information is becoming more fierce. Modern war is a combination of land, sea, air and space under the condition of information, and efficient and reliable military communication is one of the key factors to win the war. The jamming means and jamming patterns of the enemy for military wireless communication are also developing. In order to resist these constantly changing interference, various anti-jamming methods come into being. Various anti-jamming techniques and measures in spread spectrum, non-spread spectrum, time domain, frequency domain and power domain are different from each other because of their anti-jamming mechanism. As a result, different jamming signals can be resisted, but due to the constant changes in the means of jamming by the enemy, the forms of interference are changing from fixed to dynamic, from suppressing jamming to dexterous interference. Among them, the dynamic jamming mode poses a greater threat to the military wireless communication, and also puts forward a new challenge to the communication anti-jamming. However, the traditional jamming methods are mostly by changing some characteristics of the transmitted signal to carry out anti-jamming. If we can understand the characteristics of some parameters of the jamming signal and avoid the interference according to these characteristics, it will be a very effective anti-jamming method. At present, there are various forms of enemy jamming, and there are different anti-jamming methods for different jamming. Many scholars have also carried out simulation analysis and research on these anti-jamming means, but these simulation and analysis methods are carried out independently. It is difficult for the user to compare the effects of different anti-jamming methods and the anti-jamming simulation effects. Therefore, if the interference means, the accuracy of the parameters extracted and the anti-jamming effects can be comprehensively analyzed, It will be of great practical significance to develop an anti-interference simulation experimental platform which can synthesize all kinds of simulation. Firstly, this paper briefly analyzes the background, purpose and significance of the research, and discusses the main contents of the development of anti-jamming simulation experimental platform, as well as the research ideas and methods. Secondly, according to the demand of anti-jamming simulation platform, this paper analyzes the interference signal model and its mathematical expression, analyzes the main algorithm of feature parameter extraction of interference signal and the principle of communication anti-jamming technology. Anti-jamming algorithms and related problems provide a theoretical basis for the development of simulation platform. Thirdly, based on the introduction of Matlab simulation software, the requirements of communication anti-jamming simulation platform are summarized and analyzed, and the basic structure of the software and the main contents and objects of design are given. The basic program of communication simulation and the program of jamming signal and anti-jamming algorithm are written independently. The simulation program is debugged and tested, the interface of simulation platform is developed, and the simulation results of anti-jamming are given by using the platform. The results are analyzed. Finally, this paper summarizes and analyzes the work of the paper, and points out the problems that need further study.
