摘　　要：目前同步序列抗侦收能力弱,容易被检测和截获,截获后被破译分析,面临严重的信息安全风险,为了应对该风险,论文提出了一种基于混沌理论的同步序列生成方法,该方法利用复合型混沌映射生成同步序列集,利用级联型混沌映射从同步序列集中抽取得到每次发送的同步头。仿真分析显示,基于混沌理论生成的同步序列具有优良的随机特性和相关特性,且每次发送时的同步头随机变化,不可预测。At present,the anti-detection ability of the synchronization sequence is weak,and it is easy to be detected and intercepted. After interception,it is deciphered and analyzed,and facing serious information security risks,in order to deal with this risk,this paper proposes a synchronization sequence generation method based on chaos theory. This method uses a composite chaotic map to generate a synchronization sequence set,and uses a cascade chaotic map to extract the synchronization header for each transmission from the synchronization sequence set. Simulation analysis shows that the synchronization sequence generated based on chaos theory has excellent random characteristics and related characteristics,and the synchronization head changes randomly every time it is sent,which is unpredictable.
