Abstract
Official abstract text for this publication.
A system includes a radar antenna and a radar controller. The radar controller generates two narrowband radar signals, each narrowband radar signal having substantially constant frequency, the frequencies of the two narrowband radar signals differing from one another. The controller operates the radar antenna to transmit each of the generated narrowband radar signals as a transmitted signal, each transmitted signal being characterized by a transmitted power. The controller also measures a received power of received signals that are received by the radar antenna, each received signal including a portion of a corresponding one of the transmitted signals that was returned from an object or from a calibration surface at a known calibration range. A processor operating in accordance with programmed instructions calculates a range to the object on the basis of the transmitted and received powers.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: transmitting a first transmitted narrowband radar signal having a substantially constant first frequency, the first transmitted narrowband radar signal being characterized by a first transmitted power; concurrently transmitting a second transmitted narrowband radar signal having a substantially constant second frequency, the second transmitted narrowband radar signal being characterized by a second transmitted power; measuring a firs…
