| 摘 要： | 研究了MIMO(Multiple Input Multiple Output)阵列的发射波束设计问题,通过仿真研究比较了几种窄带发射信号设计方法的性能.针对宽带信号发射波束设计问题,在发射能量约束条件下提出了三种宽带发射信号设计的方法:常规最小二乘波束图匹配方法,目标方位互相关系数最小化方法和最低旁瓣方法.通过目标函数和约束条件的等效变换将波束图设计问题转换为半正定锥优化问题,并采用高效凸优化算法求解,有效降低了高维优化问题的运算量. |

| Abstract: | Unlike standard phased-arrays,MIMO arrays can choose transmit signals freely via its transmitters.In this paper we exploit the flexibility of transmit wideband signals to design desired beampatterns.Two criteria namely beampattern matching and minimum sidelobe are proposed to constrain the cross-relation matrix of wideband transmitting signals.Convex optimization techniques are used to find the numerical solution of the resulted optimization problem.Simulations show that our method is effective and promising. |
| Keywords: | MIMO broadband beampatterns positive semidefinite cone |
