G01S13/784 - 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 reradiation of radio waves, e.g. secondary radar systems; Analogous systems wherein pulse-type signals are transmitted discriminating between different kinds of targets, e.g. IFF-radar, i.e. identification of friend or foe; Secondary Surveillance Radar [SSR] in general Coders or decoders therefor; Degarbling systems; Defruiting systems
