AWARDEE OF TECHNOLOGICAL SCIENCES PRIZE

ZHANG ZHIZHONG

Abstract

Zhang Zhizhong, a radar specialist, was born in Haining, Zhejiang Province in 1917. He is a senior technical consultant in Nanjing Research Institute of Electronics Technology (NRIET). He was selected and invited to be the member of the Chinese Academy of Engineering in 1994.
Zhang Zhizhong graduated from Zhejiang University in 1940, and then worked in Chongqing Electrical Appliance Company. From 1945 to 1947, as an visiting scholar he went to England and studied in Lesceiter University for ultra-high frequency and microwave frequency and then went to Royal Electrical Mechanical Engineering College learning several types of radar that had been used in the second world war. In Oct. 1947 he returned to China. In 1950 he received an order from Beijing requiring him to Nanjing Radar Research Institute (afterward changed to NRIET). From 1951 to 1953, he had been repairing the radar that were left in China by America and Japan after the war. In 1955, he became the director of the design department, in charge of designing two types of meter band long range surveillance radar and one type of medium range microwave radar. In 1961, he was in charge of the research and development of the monopulse radar. In 1964, a monopulse radar had been manufactured, which is the first one in China. Therefore, from 1965 on, NRIET had received many items and manufactured more than thirty monopulse radar used in the missile and satellite firing ranges and the tracking ranges of their returning trajectory to the earth. In 1964, NRIET was ordered to research and develop the early warning radar for the long range missile firing by the enemy, so he was proposed to research and develop long range two dimensional scanning phased array radar and was in charge of it. In 1980, as the chief engineer of NRIET, he was in charge of the research and development of the airborne pulse doppler radar. The design was completed and several hard nuts were nearly cracked when he became a senior technical consultant in 1983. As a technical consultant, he still very concern the airborne pulse doppler radar and he himself research air-to-ground pulse doppler sharpening technique that the America was unwilling provide the technique to China. The pulse doppler sharpening technique had been solved by him and his colleagues and had already put on two types of airborne pulse doppler radar that NRIET have been manufactured. In 1987, he engaged in 863-308 about the research of inverse synthetic aperture radar (ISAR). Several years later, he obtained the flying aircraft picture and get award. He is the guest professor of three universities, in charge of doctoral degree. He has published two books and more than forty technical papers.
