On the morning of January 8, 2019, news came from the 2018 National Science and Technology Award Conference held in the Great Hall of the People. Liu Yongtan, academician of the Chinese Academy of Sciences and academician of the Chinese Academy of Engineering, and Qian Qihu, academician of the Chinese Academy of Engineering, jointly won the 2018 National Supreme Science and Technology Award.
The two winners of this years National Highest Science and Technology Award are engineering and technical experts, and the basic scientific research field continues to miss the award. Among them, Professor Liu Yongtan of Harbin University of Technology is an expert in radar and signal processing technology, and Professor Qian Qihu of Army Engineering University is an expert in protection engineering and underground engineering.
Liu Yongtan has been devoting himself to the teaching and research of electronic engineering for a long time, especially to the research of new radar system and signal processing technology. He is the founder of the theoretical system of new radar system for sea detection in China.
Qian Qihu has presided over a number of major national and military scientific research tasks, as well as the calculation of the protective door of the hangar with the highest resistance and the largest span at the time of the Zhuhai Battery Mountain blasting, which is the largest in charge volume in Asia. He has made outstanding scientific research work in the fields of engineering protection, rock mechanics and underground space development.
Winners of the 2018 National Highest Science and Technology Award
Liu Yong Tan
Founder of New System Radar Theory System for Sea Detection in China
Liu Yongtan, born in Nanjing on December 1, 1936, was born in Wuhan, Hubei Province. He is a male and Han nationality. He is an expert in radar and signal processing technology and a member of the Communist Party of China. From 1953 to 1958, he studied at Harbin University of Technology and Tsinghua University. Professor, Harbin University of Technology. He was the Dean of Graduate School of Harbin University of Technology. He was elected as a member of the Academy of Chinese Academy of Sciences in 1991 and the first batch of academicians of Chinese Academy of Engineering in 1994. He is one of the few double-material academicians.
Liu Yongtan won three National Science and Technology Progress Awards in 1991, 1997 and 2015. He has been devoted to the teaching and research of electronic engineering for a long time, especially to the research of new radar system and signal processing technology. In the field of radar system and signal processing technology, it has profound attainments and achieved a series of important scientific research results. It is the founder of the theoretical system of the new system of sea detection radar in China. Chinas first new radar station was built in the 1980s and won the first prize (first prize) of the National Science and Technology Progress Award in 1991. Since 1987, Liu Yongtan and his colleagues have also undertaken the development of a new radar system for the National 863 Project. Liu Yongtan led the research team and the relevant research institutes of China Aerospace Industry Corporation to successfully develop the first experimental radar in China, which laid a solid foundation for the further development of radar technology in China.
In the 1990s, Liu Yongtan undertook the major research project of Inverse Synthetic Aperture Radar (ISAR) in the National 863 Program, developed the theory of motion compensation, and proposed a new compensation theory for wide bandwidth signals and systems. The first experimental ISAR in China was successfully developed by leading the research team and the relevant research institutes of China Aerospace Industry Corporation, which laid a solid foundation for the further development of ISAR technology in China. The project has reached the international advanced level in the 1990s and won the second prize of the National Science and Technology Progress Award in 1997 (second place).
Liu Yongtan has successfully developed the only radar equipment with all-day, all-weather, over-the-horizon, sea-air compatibility for sea detection capability in China, which makes Chinas sea long-range early warning technology into the forefront of the world. In 2014, he won the first prize for national defense science and technology progress (first prize) and the first prize for national science and technology progress (first prize) in 2015.

Qian Qi Hu
Chinas Leader in Protective Engineering
Qian Qihu was born in Kunshan, Jiangsu Province, on October 26, 1937. He is an expert in protective engineering and underground engineering in China. He graduated from the Military Engineering College of the Chinese Peoples Liberation Army (Kazakhstan Military Industry) in 1960 and went to Moscow to study at the Gubishev Military Engineering College in 1961, where he received an associate doctorate. He is currently a member of the Standing Committee of the CST, an advisor to the CST, an honorary member of the International Society of Rock Mechanics, and a chairman of the Society of Rock Mechanics and Engineering.

Academician Qian Qihu has made outstanding contributions to the design and calculation of our national defense engineering: in the study of anti-nuclear weapons and their effects, he has solved a series of difficulties in the design and calculation of orifice protection, large-span protective doors and shallow-buried structures in soil; for the first time in China, dynamic finite element method has been used to analyze the dynamic stress of large-span protective doors in underground aircraft hangars, and he has presided over the design and The reinforced concrete protective door of the underground hangar with the largest and highest resistance is studied. The propagation of stress loading wave and unloading wave of nuclear explosion and their interaction with structure in the composite soil layer of shallow-buried structure are studied. For the first time, a three-degree-of-freedom interaction model calculation system of Shallow-Buried Structure in soil is proposed in China. In the research of probability design theory of protective structure, it is the first time to put forward that the model will be feasible. The reliability correction factor method is combined with the second-order moment method, and the influence of various uncertainties is considered comprehensively in the analysis of structural reliability, which makes it at the international advanced level in the probabilistic design method of domestic protective structures. In the subject of the influence of fault structure on in-situ stress and in-situ motion parameters in the mid-far zone of ground-impact explosion, the isolation mechanism of fault structure and the explosive stress wave passing through the fault are discussed. Quantitative theoretical analysis and simulation test of energy dissipation attenuation in fractured zone were carried out, and the dynamic contact model of explosive stress wave passing through fault lens zone was innovated. As the General Commander of engineering, he and his colleagues jointly studied the project and implemented the Zhuhai Fortress Hill chamber blasting with the largest charge quantity in Asia, which created a new world record of multi-layer and multi-row strip charge blasting.
