Abstract
Transformation principle of a time scale for time delay measurement in radar distance ranger which is analogue to the methods used in stroboscopic oscilloscopes, is considered in the article. Structural diagram of a stroboscopic radio frequent modulator is given and its basic features are identified.
Keywords
