摘　　要：针对多输入多输出(MIMO)雷达波形设计的特殊要求,本文将混沌理论应用于MIMO雷达的波形设计中,设计了基于混沌序列的跳频编码波形。该编码方式省略了波形序列寻优过程,使雷达波形设计问题得到了很大程度的简化。仿真结果表明,基于混沌编码的MIMO雷达波形具备良好的正交性,并具有类似图钉形的模糊特性,是一种理想的雷达信号。Considering special requirements of multi-input multi-output （MIMO） radar waveform design, a new method for chaos theory to MIMO radar waveform design is proposed. Frequency-hopping codings based on chaotic sequences are designed. This program omits the optimization process of waveform sequences, so that the radar waveform design problem has a high degree of simplification. Simulation results prove that MIMO radar waveforms based on chaotic sequences have good orthogonality. And the ambiguity function can resemble a thumbtack in the time-delay/frequency-shifted plane.
