摘要
现有方法中,混沌信号在MIMO雷达波形设计中的应用仅局限于单一混沌映射模型,难以改善固有缺陷。为解决此问题,设计基于Lorenz和Bernoulli 2种映射的MIMO雷达混沌调频信号,通过对信号模型、相关函数、模糊函数和综合性能的分析,证明该设计方法的可行性,表明基于两种映射的混沌调频信号通过优势互补可有效改善MIMO雷达性能。
The application of chaotic signal in multiple input and multiple output （MIMO） radar wave design is mainly limited to a single model of chaotic map at present. Its inherent disadvantages can be hardly improved. To solve the problem, a method to design a chaotic frequency modulated signal of MIMO radar by two kinds of map is presented, and Lorenz map and Bernoulli map are made as exam- ples. The analysis of the model, correlation function, ambiguity function and comprehensive performance prove the feasibility of the method, and indicate the effectual improvement of the performance of MIMO radar by complement each other＇s advantages.
