ADAPTIVE DIGITAL SPECTRAL PURPOSE SELECTOR Russian patent published in 2017 - IPC F41G3/00 F42B15/00 F42B15/01 

FIELD: physics.

SUBSTANCE: spectral purpose selector includes an electro-optical tracking hydro-coordinator with three channels of the optical radiation spektro-separation, three photodetectors, three pulse amplifiers with single differentiation, the outputs of which are connected to the amplitude detectors, and the detector outputs - to the circuit comparing the levels, or the level ratio calculators, and the comparing circuit outputs, or the relation calculators - to the circuit of detecting and forming "strobes" belonging of the target signals or interference. Herewith the serially connected signal correctors, the voltage dividers, the comparators and analyzers with the variable logic switching functions controlled with the code, are entered in each channel in the form of the second differentiation device and the binary quantizer. Also the factor dividing setpoint of the dividers and the logic analyzer functions are entered, wherein the first setpoint output is connected to the divider control input, and the second one - to the setpoint input of the analyzer logic functions .

EFFECT: high measurement accuracy.
