RAILWAY BRIDGE MASKING METHOD Russian patent published in 2022 - IPC F41H3/00 

FIELD: railway bridge masking methods.

SUBSTANCE: claimed invention relates to methods for the combined masking of a railway bridge from radar and optoelectronic means of homing cruise missiles during combat operations. To mask the railway bridge, radio-absorbing material is laid on the pontoons of the floating bridge, in the form of a grass cover, in the following sequence - three pontoons with radio-absorbing material, the next one pontoon without radio-absorbing material, next to the last pontoon at a distance of 40-45 m, metal interference masks are installed frames, which are made in the form of a false bridge and are located next to the railway bridge. Metal frame structures are attached to the existing camouflaged railway bridge. To imitate the radar signs of a false bridge, a metal mesh is used, on the surface of which strips of material are reinforced that imitate the presence of braces and crossbars in the optical range in the upper part of the railway bridge.

EFFECT: fixation of the false bridge in the optical and radar spectrum of the cruise missile guidance means is provided, while the visibility of the railway bridge in the indicated ranges is reduced.
