论文摘要
在本文中，我们描述了一对多相编码波形的演变，用于在天气雷达中第二次抑制。在NASA天气雷达上设计和测试了多相代码。 NASA双频，双极化多普勒雷达（D3R）主要是作为GPM卫星双频雷达的接地验证工具。最近，D3R雷达升级了数字接收器硬件和固件的新版本，该版本支持更大的滤波器长度和多个相位编码的波形，并且如果子系统也更新。这增强了雷达歧管的能力。
In this paper, we describe the evolution of a pair of polyphase coded waveform for use in second trip suppression in weather radar. The polyphase codes were designed and tested on NASA weather radar. The NASA dual-frequency, dual-polarization Doppler radar (D3R) was developed primarily as a ground validation tool for the GPM satellite dual-frequency radar. Recently, the D3R radar was upgraded with new versions of digital receiver hardware and firmware, which supports larger filter lengths and multiple phase coded waveforms, and also newer IF sub-systems. This has enhanced the capabilities of radar manifolds.
