摘要

波形分集是多输入多输出(MIMO)雷达的主要特征之一,设计性能良好正交波形集是实现MIMO雷达的关键技术.介绍了噪声MIMO雷达的基本原理,分析了利用混沌序列设计正交波形的可行性,提出了基于混沌序列的MIMO雷达正交波形集设计方法,给出了基于两种典型混沌序列设计二相编码正交波形的设计结果,分析了波形集相关性能,计算机仿真表明,该方法在算法效率和波形多样性方面优于传统的遗传算法.%Waveform diversity is the primary characteristics of MIMO radar and the design of orthogonal waveform set is the key to realize MIMO radar system. After introducing the principle of noise MIMO radar, a new method based chaotic sequence is proposed to design orthogonal waveform for MIMO radar. The design results of binary code waveform set based on two typical chaotic sequences are discussed. The simulations indicates the superiority than GA in arithmetic efficiency and waveform amount.
