LASER SURVEILLANCE SYSTEM Russian patent published in 2022 - IPC G01S7/497 G01S17/89 

FIELD: surveillance.

SUBSTANCE: invention relates to optoelectronic remote sensing systems, to laser surveillance systems. Laser surveillance system includes a pulse laser; an output optical system of the transmitting channel, forming collimated laser beams using the diffraction grating; a photoreceiving apparatus of a single-row line of photoreceiving sensing elements; a single-coordinate scanning apparatus; an optical objective, and a computing apparatus, an additional deflector and a control apparatus are introduced into the transmitting channel, an additional deflector is installed at the output of the transmitting channel; signals proportional to the true geometric altitude of flight, the frequency of line scanning, and the current value of the scanning angle are supplied to the input of the control apparatus and used by the control apparatus to form a control signal u(α), wherein α is the angle between the direction of propagation of laser illumination emission and the direction of reception of reflected laser emission; the additional deflector performs spatial spacing of the directions of laser illumination and reception of reflected laser emission by an angle α with the scanning frequency.

EFFECT: reduction in the impact of the laser illumination emission reflected by the atmosphere on the quality of the formed image.
