ACTIVE FALSE TARGET FORMATION METHOD IN RANGE Russian patent published in 2019 - IPC G01S17/88 

FIELD: optoelectronic equipment.

SUBSTANCE: invention can be used in laser location systems, optoelectronic countermeasures systems. Method of active false target formation by range is based on installation on object of laser transceiving device, reception of spontaneous emission of transmitting laser of range finder by laser transmitting-receiving device and measurement of its time and energy parameters, determining, based on their values, the moment of reception of radiation of the main pulse of the transmitting laser of the range finder t_O and required energy and time parameters of interference laser pulses sequence, generation and radiation by laser transceiving device in time interval Δt_P, equal to t_C<Δt_P<t_O, with the required energy and time parameters of the random sequence of interference laser pulses at the wavelength of the transmitting laser of the range finder in the direction of the laser range finder, where t_C is the moment of spontaneous emission of the transmitting laser of the range-finding device, the radiation of the random sequence of interference laser pulses is stopped by the transceiver device at the time of receiving the main pulse of the transmitting laser of the range finder t_O and resuming radiation of random sequence with duration Δt_P interference laser pulses by a transceiver device at a time equal to t_O+Δt, where Δt is average interval between impulses of sequence of interference pulses.

EFFECT: high efficiency of interference to laser range finders.
