This paper deals with constant modulus waveform design in spectrally dense environments assuming a discrete phase code alphabet. The goal is to optimize the radar detection performance while rigorously controlling the injected interference energy within each shared band and enforcing a similarity constraint to manage some relevant signal features. To tackle the resulting NP-hard optimization problem, an iterative procedure characterized by a polynomial computational complexity, is introduced leveraging the coordinate descent method. Numerical results are provided to show the effectiveness of the technique in terms of detection performance, spectral shape and autocorrelation features.

多谱约束下恒模离散相位雷达波形设计


本文讨论了假设离散相位代码字母表的频谱密集环境中的恒模波形设计。目标是优化雷达检测性能，同时严格控制每个共享频段内注入的干扰能量，并强制执行相似性约束来管理一些相关信号特征。为了解决由此产生的 NP 难优化问题，利用坐标下降法引入了以多项式计算复杂度为特征的迭代过程。提供的数值结果显示了该技术在检测性能、频谱形状和自相关特征方面的有效性。
