  • Eyesafe coherent laser radar for velocity and position measurements
    Patent number: 5237331
    Abstract: A coherent laser radar system operating at an eyesafe wavelength above 1.4 microns has been provided for measurement of the position and velocity of hard targets and aerosol targets, said system comprising a frequency-stable master laser and an injection-seeded Q-switched slave laser for generating signals for transmission to the target. Means for obtaining highly accurate velocity and range measurements are provided. Data from signal transmissions and receptions taken over a range of angles are analyzed to map target positions and velocities in time and space.
