G01S13/40 - CPC Classification

Classification description:

Systems using the reflection or reradiation of radio waves, e.g. radar systems; Analogous systems using reflection or reradiation of waves whose nature or wavelength is irrelevant or unspecified; Systems using reflection of radio waves, e.g. primary radar systems; Analogous systems; Systems determining position data of a target; Systems for measuring distance only using transmission of continuous waves, whether amplitude-, frequency-, or phase-modulated, or unmodulated with phase comparison between the received signal and the contemporaneously transmitted signal wherein the frequency of transmitted signal is adjusted to give a predetermined phase relationship
