| 摘 要： | MIMO雷达相对于传统的相控阵雷达，可以更自由地选择发射波形来匹配所需要的发射方向图。文中首先给出了一个带有限制条件的优化问题以寻找发射信号的协方差矩阵，从而能够在空间匹配理想的方向图，接着建立了一组恒模的二相离散序列来匹配已有的协方差矩阵，并将这种方法推广到多相码设计中，并对实验结果进行了详细分析。

| Abstract: | Waveform diversity enables the MIMO radar to choose the transmit waveforms more freely to match the desire transmit beampattern than the traditional phased-array radar.In this paper,a constrained optimization problem is first proposed to find a Cross-Correlation matrix which causes the true transmit beampattern to be close in some sense to a desired beampattern.The second is the problem of designing multiple constant-modulus binary phase waveforms with given cross-correlation matrix.It is also shown that th... |
