    Groups G01S 13/00-G01S 17/00cover:[3]
      systems for detecting the presence of an object, e.g. by reflection or reradiation from the object itself, or from a transponder associated with the object, for determining the distance or relative velocity of an object, for providing a co-ordinated display of the distance and direction of an object or for obtaining an image thereof;systems arranged for mounting on a moving craft or vehicle and using the reflection of waves from an extended surface external to the craft, e.g. the surface of the earth, to determine the velocity and direction of motion of the craft relative to the surface.
    Groups G01S 13/00-G01S 17/00 do not cover:
      systems for determining the direction of an object by means not employing reflection or reradiation, which are covered by groups G01S 1/00 or G01S 3/00;systems for determining distance or velocity of an object by means not employing reflection or reradiation, which are covered by group G01S 11/00.
