提出了一种在密集MIMO雷达系统中实现给定协方差矩阵的恒包络（CE）波形生成方法。与现有的算法相比，该技术提供了用于找到所需波形的封闭形式的解决方案，并建议波形可以从有限的字母表中选择，例如二进制相移键控（BPSK）和正交相移键控（QPSK）。使用无记忆非线性函数将高斯随机变量（RV）映射到CE非高斯RV。建立了非线性函数输入端的高斯RV与输出端的非高斯RV之间的相关关系。仿真结果证明了该方法的有效性。
A method for generating constant envelope (CE) waveforms to realise a given covariance matrix for a closely spaced MIMO radar system is proposed. In contrast to available algorithms, the technique provides closed form solutions for finding the required waveforms and suggests that waveforms can be chosen from finite alphabets such as binary-phase shift keying (BPSK) and quadrature-phase shift keying (QPSK). Gaussian random-variables (RV's) are mapped onto CE non-Gaussian RV's using memoryless non-linear functions. The relationship between the correlation of Gaussian RV's at the input to the nonlinear functions and non-Gaussian RV's at their output is established. Simulation results are presented to demonstrate the effectiveness of the methodology.
