METHOD FOR DETERMINING DIRECTION TO SOURCE OF OPTICAL RADIATION ON BASIS OF COMPONENT, DISSIPATED IN ATMOSPHERE, AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G01S17/06 

FIELD: quantum electronics, possible use in systems for trajectory measurements, and also systems for precisely determining direction towards sources of optical radiation for air-based equipment.

SUBSTANCE: in accordance to method, second optical-electronic coordinator with matrix photo-receivers is additionally installed, field flatness of which is perpendicular to field plane of first optical-electronic coordinator, coordinate alignment of photo-elements of first optical-electronic coordinator is performed in coordinate plane x0z and of photo-elements of second optical-electronic coordinator in coordinate plane y0z, determining of angular coordinates of optical radiation source on basis of formulae where ε, β - tilt angle and azimuth of optical radiation source; d - distance between upper and lower lines of photo-elements of optical-electronic coordinator; Δx=x_1B-x_1H, Δy=y_2B-y_2H; x_1B and x_1H - coordinates of upper and lower photo-elements of lines of first coordinator, signal at output of which has maximal value; y_2B and y_2H - coordinates of upper and lower photo-elements of lines of seconds coordinator, signal at output of which has maximal value. Device for realization of method consists of first and second optical-electronic coordinators with matrix photo-receivers, first and second subtraction blocks, first and second square-law generators, first and second dividers, adder, square root extractor block, first and second arctg calculation blocks, outputs of which are outputs of device, while first and second outputs of optical-electronic coordinator are connected respectively to first and second inputs of first subtraction block, first output of which is connected to input of first square-law generator, second output - to first input of first divider, first and second outputs of second optical-electronic coordinator are connected respectively to first and second inputs of second subtraction block, first output of which is connected to input of second square-law generator, second output - to second input of first divider, output of first divider is connected to input of first arctg calculation block, outputs of first and second square-law generators are connected to appropriate inputs of adder, while output of adder is connected to input of square root extractor block, output of which is connected to first input of second divider, onto second input of which value d is fed, output of divider is connected to input of output arctg calculation block.

EFFECT: increased energy and interference resistance of determining of direction towards source of optical radiation.
