摘　　要：传统的优化算法需要进行组合优化过程,存在算法复杂、耗时的问题,为此,设计了能够快速获得MIMO(Multiple Input and Multiple Output)雷达正交相位编码信号的方法。基于混沌映射信号良好的相关特性和类随机特性,对Henon和Logistic混沌映射序列进行采样截取和二值量化得到二相码元,最后调制得到正交相位编码信号。仿真结果表明,利用这两种混沌映射序列可以快速获得符合条件的正交相位编码信号。A fast method for orthogonal phase coded signals of MIMO（Multi - input Multi - output） radar is proposed to solve the problem that traditional optimization algorithms are complicated and time wasting because of combinatorial optimization. Based on chaotic map signals which get perfect property of correlation and randomness, binary phase codes are obtained by choosing and binarying sequences generated from Henon and Logistic map seties. Then they are modulated to orthogonal phase coded signals. Simulation and analysis prove that it is fast to introduce Henon and Logistic map sequences into the design of appropriate orthogonal binary phase coded signals.
