Recently, the 2023 Guangzhou Smart Meteorological Equipment Exhibition closed at the Guangdong-Hong Kong-Macao Greater Bay Distinction Center of the World Meteorological Center (Beijing). The WDCPT0164 C- band dual-polarization (dual-polarization) active phased array weather radar independently developed and manufactured by Guangdong Narui Radar Technology Co., Ltd. (hereinafter referred to as "Narui Radar", stock code: 688522) made its debut on the spot. Zhang Wenjian, Assistant Secretary General of the World Meteorological Organization (WMO), senior managers and senior meteorologists of meteorological and hydrological departments (NMHS) in more than 30 countries around the world, as well as a group of international and domestic famous experts and business technicians of meteorological related units, witnessed the release of new products on the spot.

Dual-polarization (dual-polarization) phased array weather radar is a weather radar that uses a polarized phased array system. Dual-polarization (dual-polarization) phased array weather radar has the advantages of fast scanning ability and polarization detection ability, and is one of the important technical development directions of future weather radar. The detection frequency bands of weather radar mainly include S-band, C- band and X-band. With the development of weather radar technology in China, X-band dual-polarized phased array weather radar has been widely used in meteorological monitoring, and has been proved to have significant advantages in small and medium-scale strong weather monitoring and early warning. In addition, S-band dual-polarized phased array weather radar has also entered the experimental stage. The new release of the WDCPT0164 C- band dual-polarized (dual-polarized) active phased array weather radar makes up for the vacancy of the C- band microstrip patch antenna dual-polarized phased array weather radar, becoming the world's first publicly released C- band weather radar using the microstrip patch antenna dual-polarized (dual-polarized) phased array technology system.

the WDCPT0164 c-band dual-polarization (dual-polarization) active phased array weather radar adopts the phased array antenna technology of all-digital DBF architecture, has the multi-beam fast scanning capability, and can complete a body scan within 60 seconds. compared with products such as c-band dual-polarization mechanical weather radar and single-polarization c-band phased array weather radar. The WDCPT0164 C- band dual-polarized active phased array weather radar has the advantage of higher space-time resolution, stronger vertical detection ability of weather system, and has the ability of polarized particle phase recognition, polarization anti-clutter ability and accurate quantitative rainfall measurement ability. Compared with X-band dual-polarized phased array weather radar and S-band dual-polarized phased array weather radar, WDCPT0164 C- band dual-polarized active phased array weather radar not only has the fine detection ability of X-band weather radar, but also has the ability of long-distance monitoring and early warning of S-band radar, which has the characteristics of strong comprehensive detection ability and high cost performance, it is widely used in weather radar business monitoring, airport terminal weather detection, small and medium-scale severe convective weather monitoring and early warning, surface rainfall monitoring and other business fields. WDCPT0164 C- band dual-polarization (dual-polarization) phased array weather radar and X-band dual-polarization phased array weather radar network collaborative monitoring can not only realize 1-minute update, fine rainfall echo monitoring with full airspace coverage, but also realize inversion of ultra-large-scale three-dimensional wind field, form a high spatial and temporal resolution weather radar monitoring network that takes into account both large-scale monitoring and local fine monitoring, and further improve the monitoring and early warning capability of the radar network.

Meteorological radar is an important indicator to measure the level of meteorological modernization capabilities, and it is also one of the core weapon to support the high-quality development of meteorological undertakings. In recent years, with the great-leap-forward development of social economy and scientific and technological level, the operation guarantee ability of radar meteorological business in China has been gradually improved. As an important part of meteorological business, meteorological radar has played an important role in improving the ability of monitoring and early warning of sudden and disastrous weather, and has become an effective technical means for early warning and prevention of meteorological disasters in China. With the new appearance of the C- band dual-polarization (dual-polarization) phased array weather radar independently developed by my country, the application of dual-polarization phased array weather radar will open a new chapter and help my country's meteorological disaster prevention and mitigation capabilities to further improve.
