METHOD FOR LASER LOCATION AND SELECTION OF MOBILE TARGET Russian patent published in 2015 - IPC G01S13/00 

FIELD: physics, optics.

SUBSTANCE: invention relates to laser engineering and can be used in optical location of high-speed objects. In a method for laser location of a mobile target, based on generating and receiving laser radiation reflected from a target, interference modulation of the received radiation, conversion thereof into an electrical signal and subsequent processing of the signal, interference modulation of the received radiation is carried out by mixing with radiation of the laser source, converting the modulated oscillations into an electrical signal and then into a digital code by sampling, performing spectral analysis of the obtained digital signal, measuring the Doppler velocity of the target, selecting a target by comparing the measured Doppler velocity of the target with a given velocity, calculated from predicted data, using the comparison results to determine presence of a target with given parameters in space, wherein calculation of the Doppler velocity of the target takes into account the results of measuring Doppler velocities of other targets, as well as deviation of the real trajectory of approach with the target from the predicted trajectory; converting the electrical signal into a digital code by sampling the signal with a period shorter than the period of the modulated oscillations.

EFFECT: high efficiency of optical location and selection of high-speed targets in an environment with interference.
