Title: **Xu Han: Innovator and Patent Holder in Radionuclide and Weather Radar Technologies**
Introduction
Xu Han is a prominent inventor based in Beijing, China. With an impressive portfolio of 19 patents, his contributions to the fields of radionuclide preparation and weather radar technology have garnered significant attention and recognition. As a forward-thinking innovator, Han continues to push the boundaries of engineering and technology.
Latest Patents
Among Xu Han's latest patents is a **solid target system for radionuclide preparation**. This innovative system includes a cassette, an ejection sub-system, a laser radar positioning sub-system, a cooling sub-system, and a control cabinet. The cassette features a solid target component crucial for nuclide preparation, along with a shielding box. The ejection sub-system efficiently ejects the cassette into a recovery hole upon completing the nuclide preparation process. The laser radar positioning sub-system, positioned above the ejection sub-system, is electrically connected to the control cabinet, enhancing operational precision. Each side of the cassette is equipped with the cooling sub-system to maintain optimal temperatures for the solid target component. The control cabinet interfaces with a direct-current servo motor to oversee the system's operational state.
Additionally, Han holds a patent for a **dual-polarized phased array antenna and dual-polarized phased array weather radar**. This design comprises multiple dual-polarized row feeds arranged on a horizontal cylindrical support, enabling simultaneous reception and transmission of two polarized signals—one horizontal and one vertical. This technology ensures digital multi-beam signals that deliver consistent beam bandwidth, antenna gain, and dual polarization performance. The dual-polarized phased array weather radar utilizes either a dual-polarized microstrip patch antenna or a waveguide slot antenna, improving weather detection consistency across various scan angles. This advancement enhances the accuracy of weather target 3D construction and simplifies the calibration processes required for existing phased array weather radars.
