METHOD FOR IMITATING REFLECTION SURFACES OF OPTOELECTRONIC DEVICE Russian patent published in 2024 - IPC G01S17/02 

FIELD: optoelectronic technology.

SUBSTANCE: invention can be used in laser location systems, optoelectronic countermeasure systems. The method for simulating reflection surfaces of an optical-electronic device is based on installing a false optical target in the search sector of an optoelectronic device, including N optical corner reflectors of the tetrahedral type with right angles at the apex, having a common input plane. In this case, the height of the n-th optical corner reflector is greater than the height of the n+1-th optical corner reflector by a length that provides a delay of laser ranging radiation, similar to the delay of laser ranging radiation between the n-th and n+1-th reflective surfaces of the simulated optoelectronic device, where and the reflective surfaces of the n-th and n+1-th optical corner reflectors have values of generalized reflection coefficients equal to the values of the reflection coefficients of the corresponding n-th and n+1-th reflective surfaces of the simulated optoelectronic device, and reflection of laser ranging radiation by each optical corner reflector of a false optical target and imitation of the spatial sequence of reflective surfaces of an optoelectronic device. In this case, N optical corner reflectors are installed so that one of their three edges lies on a common straight line.

EFFECT: increase in the efficiency of a false optical target (FOT) with imitation of the spatial sequence of reflective surfaces of an optoelectronic device (OED).
