Communications: directive radio wave systems and devices (e.g., radar, radio navigation)

SECTION I - CLASS DEFINITION

STATEMENT OF THE CLASS SUBJECT MATTER:

A. Systems and processes for transmission or reception of radio wave energy for obtaining or utilizing information (using radio wave transmitters or receivers), as to an object, or as to the directional characteristics of the radio wave energy, per se.

B. This class includes radar systems wherein radio wave energy from a transmitter is reflected or otherwise returned from an object to a receiver which may be at the same location as the transmitter.

C. This class includes subsystems, components, and related processes which are limited to use in connection with the above and not provided for elsewhere.

D. This class is limited to electromagnetic radio frequency waves in the radiation field. Radiation waves produces by lasing (coherent addition) action and induction field electromagnetic waves are excluded from this class, even though they may operate at radio frequencies. See "radio wave" definition above for other type exclusions.
