摘要
MIMO(Multiple-input Multiple-output)雷达系统的单元或子阵辐射互不相同的波形,提供了足够的自由度用于天线波束的灵活成形和捷变,可以作为常规相控阵和正交雷达信号MIMO体制的通用化推广。在研究分析具有任意互相关特性的信号集合的选择综合波束方向图的基础上,采用全局遗传模拟退火算法对MIMO雷达的波束综合问题进行了最优化搜索,仿真结果显示,该算法获得了较好的结果。
Each element or sub-array radiates different waveforms,which provides adequate freedom to agilely form and alter antenna beam.This characteristic can be considered as a generalization of familiar phased-array and orthonormal MIMO system.Based on research of beam pattern synthesis through selecting specific signal set with arbitrary cross-correlation function, applies is applied GGASA to solve the beamforming problem of MIMO radar,which achieves preferable result.
