Recently, Naruida Radar received a scientific and technological achievement appraisal certificate from the China Radar Industry Association. The appraisal committee, headed by a Chinese Academy of Sciences academician, unanimously determined that the "Research and Application of X-band Dual-polarization (Dual-polarization) Active Phased Array Weather Radar System" passed the scientific and technological achievement appraisal. The appraisal results show that the X-band active phased array (dual-polarization) radar system independently researched and manufactured by Naruida Radar has achieved internationally advanced levels in the field of meteorological radar.

On November 26, 2021, the China Radar Industry Association held a scientific and technological achievement appraisal meeting for the "Research and Application of X-band Dual-polarization (Dual-polarization) Active Phased Array Weather Radar System" project in Wuhan.

The appraisal results show that the X-band dual-polarization (dual-polarization) active phased array radar system independently researched and manufactured by Naruida Radar has high spatiotemporal resolution and high-precision weather detection capabilities. It has obvious advantages in the detection and forecasting and warning of strong convective weather systems such as thunderstorms, strong winds, short-duration heavy rainfall, tornadoes, and hail, which are small in scale, rapid in development and dissipation, and have strong disaster-causing capabilities. It can significantly improve the detection capability of small-scale strong convective weather and has important application value in meteorological disaster prevention and mitigation, short-term meteorological forecasting and warning, and refined meteorological services.

This project involves complex technology and high research difficulty. It has achieved significant technological innovations in dual-polarization microstrip patch array antennas and dual-polarization meteorological data processing technology. It possesses multiple independent intellectual property rights, with the domestic component and material ratio of core components exceeding 90%, and core technologies are independently controllable. The overall technology has reached internationally advanced levels in the field of meteorological radar.

The X-band dual-polarization (dual-polarization) active phased array weather radar system is the first domestic radar system to combine dual-polarization and phased array technology. It features precise detection, reliable data, and system stability. The time resolution of this radar system is 30s, 12 times faster than traditional weather radar, and the spatial resolution is 30X30m, 64 times higher than traditional weather radar. It can achieve more precise weather system identification and classification, high-precision three-dimensional wind field inversion, and a longer lead time for strong weather warnings.

Currently, the product has been successfully deployed and operated in many parts of China, including Guangdong, Fujian, Hunan, Sichuan, Shanxi, Shandong, Tibet, Shaanxi, Hebei, Henan, Jiangsu, Anhui, and Hong Kong. It has also successfully established the first domestic dual-polarization active phased array radar ultra-high spatiotemporal resolution weather observation network in the Guangdong-Hong Kong-Macao Greater Bay Area and has been included in the "Meteorological Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area (2020-2035)". The radar performance indicators have been verified through years of operational application, producing significant economic and social benefits, and have broad market application prospects.
