Abstract:
A laser radar system using collocated laser beams to unambiguously detects a range of a target and a range rate at which the target is moving relative to the laser radar system. Another aspect of various embodiments of the invention may relate to a laser radar system that uses multiple laser radar sections to obtain multiple simultaneous measurements (or substantially so), whereby both range and range rate can be determined without various temporal effects introduced by systems employing single laser sections taking sequential measurements. In addition, other aspects of various embodiments of the invention may enable faster determination of the range and rate of the target, a more accurate determination of the range and rate of the target, and/or may provide other advantages.

Claim (Index 38):
A method for determining a distance between a laser system and a target, the method comprising:\n generating, from a first laser source, a first laser beam having a first frequency; generating, from a second laser source, a second laser beam having a second frequency; chirping up the first frequency of the first laser beam at a first chirp rate while chirping down the second frequency of the second laser beam at a second chirp rate; directing the first laser beam and the second laser beam to be incident on the target; receiving a first reflected portion of the first laser beam from the target and a second reflected portion of the second laser beam from the target; and combining the first reflected portion of the first laser beam with the second reflected portion of the second laser beam to determine at least a range to the target, wherein combining the first reflected portion of the first laser beam with the second reflected portion of the second laser beam comprises:\n electronically combining the first reflected portion of the first laser beam with the second reflected portion of the second laser beam, or \n optically combining the first reflected portion of the first laser beam with the second reflected portion of the second laser beam, or \n digitally combining the first reflected portion of the first laser beam with the second reflected portion of the second laser beam.
