Abstract: Methods and apparatus are disclosed herein to determine relative positioning between moving platforms. An example method includes sending a first signal via a first moving platform to be received by a second moving platform. The example method includes receiving, at the first platform, a second signal sent by the second moving platform and aligning the first signal and the second signal. The example method includes determining, at the first moving platform, a first duration of time between the sending of a first pulse and the receiving of a second pulse. The example method includes determining, at the second moving platform, a second duration of time between the sending of the second pulse and the receiving of the first pulse. The example method includes determining a distance of the first moving platform relative to the second moving platform based on the first and second durations of time.

Abstract: Systems and methods for measuring a distance to an object. An exemplary method includes directing light beams from three or more continuous-wave lasers onto a target to generate an interference beam, and also frequency shifting the light beams split off from the lasers to generate local oscillator beams. When the interference beam and the local oscillator beams are combined, the method further includes determining optical phases of heterodynes produced by combining the light beams and the local oscillator beams, and determining synthetic phases by taking the difference between the optical phases of the heterodynes. The method further includes determining synthetic wavelengths based on the differences between the frequencies of the lasers. The method further includes determining a distance to the target based on the synthetic phases and the synthetic wavelengths.

Abstract: Systems and methods for determining the position of an object in a coordinate system. An exemplary system includes three or more laser ranging sensors each configured to direct a sensor beam of continuous-wave light toward a target. Light reflecting off the target interferes with the sensor beam creating an interference beam. The interference beam is combined with local oscillator beams in each laser ranging sensor to create a synthetic wave beam. Each of the laser ranging sensors also includes an array of photodetectors that sense the synthetic wave beam, and is able to measure a distance to the target based on output from the array of photodetectors. The system further includes a controller that receives a distance measurement from each of the laser ranging sensors, and calculates a position of the target in the coordinate system based on the distance measurements.

Abstract: A laser Doppler vibrometer architecture and detection technique that can remotely identify targets based on their natural vibration frequencies using a scanning Fabry-Pérot interferometer. The proposed systems and methods can have stand-off distances longer than the coherence length of the laser by using spectroscopic detection methods instead of coherent heterodyne detection using a local oscillator. Pulsed lasers can be used which have high power output. In addition, by not using an acousto-optic modulator, the speed of the detectable target is not limited. Also the mixing efficiency of the return signal can be improved.
