本文考虑了在相似度和能量约束下存在有色高斯扰动时的鲁棒波形设计问题。我们采用最大最小方法，其中最坏情况检测性能（超过可能的多普勒频移）在前面提到的约束下相对于雷达波形进行优化。所得到的优化问题是一个具有无穷多个约束的非凸二次约束规划（QCQP），一般来说是np困难的，通常难以求解。因此，我们提出了一个具有多项式计算复杂度的算法来生成上述QCQP的良好次优解。通过与一些已知雷达波形的对比分析，表明该算法的次优解可以得到高质量的雷达信号。
This correspondence considers the problem of robust waveform design in the presence of colored Gaussian disturbance under a similarity and an energy constraint. We resort to a max-min approach, where the worst case detection performance (over the possible Doppler shifts) is optimized with respect to the radar waveform under the previously mentioned constraints. The resulting optimization problem is a non-convex Quadratically Constrained Quadratic Program (QCQP) with an infinite number of constraints, which is NP-hard in general and typically difficult to solve. Hence, we propose an algorithm with a polynomial computational complexity to generate a good sub-optimal solution for the aforementioned QCQP. The analysis, conducted in comparison with some known radar waveforms, shows that the sub-optimal solutions by the algorithm lead to high-quality radar signals.
