FALSE TARGET Russian patent published in 2017 - IPC F41J2/00 

FIELD: military equipment.

SUBSTANCE: false target is made of metal pipe section (4) with one dead end and trihedral corner reflectors in the number of N pieces. The N-1 triangular corner reflectors are made of grids of thin conductors with square cells. All N angle reflectors are rigidly fixed in the body of the false target, one after the other, in order of decreasing working wavelengths of the sub-bands and coaxial to the body with apertures in the direction of the open body end. The angle reflector of the long wave sub-band is set in front of the open body end. A corner reflector of the short-wave sub-band which faces are made of metal sheets is mounted in front of the blanked end. The dimensions of cells b_i of i-th grids of faces (i=1, 2, …, N-1) of the angle reflector and the wavelengths of sub-bands of corner reflectors satisfy the inequalities: λ_(i+1)/2<b_i<λ_i/4, where i - takes values 1, 2, …, N (i - the number of corner reflectors and sub-bands of wavelengths starting from the longest wave); λ - the smallest wavelength of the first sub-band; λ_{(i +1)} - the largest wavelength of the next sub-band; b_i - the size of square cells of the grid faces of the i-th corner reflector. The distance between the adjacent i-th and (i +1) -th angular reflectors is 0.5λ_i.

EFFECT: increased number of working ranges of false target wave lengths.
