Assignee: QUALCOMM INCORPORATED
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. A method of radar measurement, the method comprising:
transmitting, via a transceiver, a first beam having a first frequency characteristic;
calculating a distance between the transceiver and a moving object based on information from at least one reflection of the first beam;
transmitting, via the transceiver, a second beam having a second frequency characteristic that is different than the first frequency characteristic, wherein the second beam is directed such that an axis of the second beam intersects a ground plane and such that the axis of the second beam is at an elevation angle with respect to the ground plane that is different from the axis of the first beam with respect to the ground plane, wherein the first frequency characteristic is a pulse repetition rate of the first beam, and wherein the second frequency characteristic is a pulse repetition rate of the second beam, and wherein the first frequency characteristic is lower than the second frequency characteristic; and
calculating an ego-velocity of the transceiver based on information from at least one reflection of the second beam.
