论文摘要
脉冲压缩可以提高范围分辨率的性能和对天气雷达的灵敏度。但是，如果不精心实施，它将引入高旁b的问题。在这一事实中，我们专注于本文中天气雷达的脉冲压缩设计。具体而言，我们基于乘数的交替方向方法（ADMM）共同设计子孔码和扩展不匹配过滤器。这种关节设计将产生低旁虫的脉冲压缩，这等效地意味着高信噪比 - 加上噪声比（SINR）和气象反射率的低估计误差。实验结果证明了所提出的脉冲压缩策略的功效，因为它达到的气象反射率估计与地面真相高度相似。
Pulse compression can enhance both the performance in range resolution and sensitivity for weather radar. However, it will introduce the issue of high sidelobes if not delicately implemented. Motivated by this fact, we focus on the pulse compression design for weather radar in this paper. Specifically, we jointly design both the subpulse codes and extended mismatch filter based on the alternating direction method of multipliers (ADMM). This joint design will yield a pulse compression with low sidelobes, which equivalently implies a high signal-to-interference-plus-noise ratio (SINR) and a low estimation error on meteorological reflectivity. The experiment results demonstrate the efficacy of the proposed pulse compression strategy since its achieved meteorological reflectivity estimations are highly similar to the ground truth.
