Chen Jingxiong, academician of the Chinese Academy of engineering and expert in electromagnetic field theory and antenna design, died in Beijing on March 16, 2022 at the age of 101.

Chen Jingxiong, born in Zhenhai County, Zhejiang Province in October 1921, graduated from the Department of electrical engineering of Shanghai Datong University in June 1947 and graduated from Shanghai Jiaotong University in June 1950. He once served as consultant of science and Technology Commission of China Aerospace Science and Industry Corporation, researcher of the second Research Institute of China Aerospace Industry Corporation, deputy director of 23 Institutes of the second Research Institute of China Aerospace Industry Corporation, part-time professor and doctoral supervisor of Peking University, Tsinghua University and Beijing University of Aeronautics and Astronautics. He was elected academician of Chinese Academy of Engineering in 1995.

Since the early 1950s, Chen Jingxiong has been engaged in the research and application of electromagnetic wave ground wave propagation, electromagnetic field theory, antenna and microwave technology. Combined with engineering practice, he put forward the direct solution theory of Maxwell equation, solved a large number of theoretical problems in microwave technology and antenna engineering, made outstanding contributions to China’s national defense communication construction, and was one of the representatives of the early development of China’s guidance radar antenna design.

Chen Jingxiong is China’s first generation astronaut. He once developed a missile antenna for China’s first domestic surface to surface missile, making the “1059” missile a “target of some”; Took the lead in overcoming the development problem of China’s first surface to air missile “543” guidance station. The guidance station was applied to the hongqi-1, hongqi-2 and hongqi-2a weapon systems, and assumed the sacred responsibility of defending the airspace of the motherland in the early days of the founding of new China; In the initial stage of the development of China’s air and space defense system, it undertook the development tasks of “101” radar, “102” radar and “715” radar, and achieved a number of important research results. A number of technologies such as phased array radar have filled the gap in China.

In 1954, Chen Jingxiong first submitted an application for joining the party to the party organization, which wrote: “to make China rich and strong, we must take developed science and technology as the premise…” in more than 70 years accompanied by scientific research, he has always adhered to such an ideal and made unremitting efforts.
