China is one of the countries that employs high‐frequency over‐the‐horizon radars for both military and civil applications. The first Chinese high‐frequency over‐the horizon backscatter radar was developed in the 1970s. This paper briefly introduces the first Chinese over‐the‐horizon backscatter radar system and reviews ionospheric backscatter and propagation studies in China. The paper discusses the motivation for establishing over‐the‐horizon radar systems in China, the experimental system, target recognition and detection,and estimation of over‐the‐horizon radar availability. Observations of aircraft, large‐scale traveling ionospheric disturbances, and the effects of a remote nuclear explosion are also presented. Finally, the real‐time Chinese ionosonde network and frequency predictions using backscatter ionograms are discussed.
