摘要:
该文采用基于现代优化理论优化发射信号的互相关矩阵的方法来形成所期望的天线发射方向图以实现发射波束成形。建立了方向图设计的数学模型,通过最小化代价函数来获得数值优化结果。采用混合遗传算法来优化选择多输入多输出(MIMO)雷达相关信号的互相关矩阵,以实现向期望空间方向图的逼近。仿真结果证明了该方法的可行性和有效性。
Abstract:
A method of realizing transmit beamforming by designing the cross-correlation matrix of transmit signals to establish a desired beam pattern is studied,which uses modern optimization theory.A mathematical model of designing a beam pattern is set up,and the method can get the optimized result by minimizing the cost function.The desired spatial transmit beam pattern can be approximated by using the hybrid genetic algorithms to optimize the cross-correlation matrix of transmit signals of multiple-input multiple-output(MIMO) radars.The simulation results testify the validity of the method.
