NONLINEAR RADAR RANGING DEVICE Russian patent published in 2018 - IPC F41H11/136 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to the field of the anti-tank mines with wide hitting zone detection technical means. Two-position device of nonlinear radar ranging consists of the transmission point with the electromagnetic field SHF emitter, acoustic field source, amplitude-modulated optical field emitter, control radio line receiver and receiving point, with the harmonics SHF receiver, selective LF recorders, the radio control line transmitter. Novelty in the nonlinear radar ranging device composition is introduction of the acoustic and amplitude-modulated optical fields sources, connected to the reflected signals harmonics SHF receiver outputs the low-frequency signals selective recorders, connected to the low-frequency signals selective recorders outputs control radio link transmitter, as well as the control radio link receiver connected to the inputs of the acoustic and amplitude-modulated optical fields sources. With the characteristic for both the WHZM and “interfering objects” signals harmonics fixing by the receiver, in the control radio line transmitter, a command is generated to switch on the acoustic field source and the amplitude-modulated optical field emitter, which is supplied to them through the control radio line receiver. If the searched object is mine with the acoustic and optical target sensors, then the exciting fields parametric action changes their non-linear reflective properties, which causes the low-frequency amplitude modulation appearance in the reflected electromagnetic field SHF harmonics, due to which the anti-tank WHZM detection in the GRRS operation zone is performed. If the searched object is the “interfering object”, then because of the acoustically and optically sensitive elements absence, false low-frequency signals do not appear. Reducing the entire device total energy consumption, weight and dimensions, as well as increase in the mines with the wide hitting zone detection secrecy of damage is implemented due to the acoustic and optical exciting fields energy-consuming sources switching on only in the SHF signal presence in the harmonics.

EFFECT: enabling the anti-tank mines with the wide hitting zone search safety and high speed with the use of non-linear radar ranging in any terrain.
