High frequency (HF)channel quality estimation equipment can be divided into two categories accord-ing to the technical system,one is independent sounding system and the other is embedded estimation system . This paper introduces the basic principles,research and application situation,and current shortages of two cate-gories of channel estimation systems,and points out that the two kinds of techniques should be combined and channel analysis should base on service in order to improve efficiency . Finally,it provides the development prospects of the technique . It is hoped that all of this can provide a reference for research on real time channel valuation for HF communications.
