提出的下一代雷达系统具有多个发射孔径，在选择每个孔径发射的信号时具有完全的灵活性。在这里，我们提出使用具有任意相互关联矩阵R的多个信号，并表明可以选择R来实现或近似期望的空间发射波束方向图。这导致了寻找R值的约束优化问题，这使得真实发射波束方向图在某种意义上接近期望波束方向图。这是通过在R的Cholesky因子空间中的梯度搜索来实现的。
Proposed next-generation radar systems have multiple transmit apertures with complete flexibility in the choice of the signals transmitted at each aperture. Here we propose the use of multiple signals with arbitrary cross-correlation matrix R and show that R can be chosen to achieve or approximate a desired spatial transmit beampattern. This leads to the constrained optimization problem of the finding the value of the R, which causes the true transmit beampattern to be close in some sense to a desired beam-pattern. This is approached using a gradient search in the space of Cholesky factors of R.
