| 摘 要： | MIMO雷达能有效地促进现代雷达的性能,由于MIMO雷达发射相互正交的信号,所以设计具有低自相关和互相关的正交信号是MIMO雷达实现的关键问题.本文基于自相关及互相关峰和能量为代价函数,提出了一种混合的优化算法来数字搜索正交多相码集,该算法包括遗传算法及叠代码选择算法.用该算法进行了仿真优化设计,仿真结果显示,提出的算法是有效性和可行的.

| Abstract: | Multiple Input Multiple Output(MIMO) radar can effectively improve radar performance by transmitting specially designed orthogonal signals.Based on the autocorrelation and cross-correlation peak and energy cost function,a novel hybrid algorithm is presented to numerically optimize such orthogonal code sets.The proposed algorithm integrates a statistical Genetic Algorithm(GA) with the traditional iterative code selection method.Simulation results show that the proposed algorithm is effective for the design o... |
