ABSTRACT As a first of its kind in India, indigenous development of dual-polarization C-Band Doppler weather radar (DWR) is discussed in the manuscript. Radar Development Area (RDA) of ISRO Telemetry Tracking and Command Network (ISTRAC) have developed the system and the DWR is installed at Thumba Equatorial Rocket Launch Station (TERLS) of Vikram Sarabhai Space Centre (VSSC) which is a centre of Indian Space Research Organization (ISRO) in the Kerala state of India. Till now, the DWRs available in India were either imported or were working on single polarization. The purpose of this DWR is to establish the technology based on polarimetric observation for meteorological and hydrological applications like intense weather monitoring and cyclone detection. The current paper mainly aims to show the DWR system-level details and the calibration approaches adopted. Some first cut data validation results are also presented for various events captured by the DWR.

印度首个自主开发的极化 C 波段多普勒天气雷达及其第一手验证结果

摘要 作为印度同类产品中的首创，手稿中讨论了双极化 C 波段多普勒天气雷达 (DWR) 的本土开发。ISRO 遥测跟踪和指挥网络 (ISTRAC) 的雷达开发区 (RDA) 开发了该系统，DWR 安装在印度空间研究中心 Vikram Sarabhai 航天中心 (VSSC) 的 Thumba 赤道火箭发射站 (TERLS)印度喀拉拉邦的组织 (ISRO)。到目前为止，印度可用的 DWR 要么是进口的，要么是用于单极化的。该 DWR 的目的是建立基于极化观测的技术，用于气象和水文应用，如强天气监测和气旋探测。目前的论文主要旨在展示 DWR 系统级的细节和采用的校准方法。还针对 DWR 捕获的各种事件提供了一些首次切割数据验证结果。
