METHOD OF CREATING RADAR REFLECTORS FOR IMITATING LINEAR OBJECTS IN LOW TEMPERATURE CONDITIONS Russian patent published in 2020 - IPC F41H3/00 H01Q17/00 

FIELD: physics.

SUBSTANCE: invention relates to methods of camouflaging objects and can be used for imitation in a radar range of wavelengths, protection from external monitoring by surveillance equipment and high-precision weapons of extended linear objects in low temperature conditions, method can also be used for production and equipment in field conditions of radar navigation landmarks and reference points. In order to create radar reflectors, snow is compacted to the required density of the front ski of the installation to form furrows for radar reflectors. Using the device for making furrows in the snow, V-shaped furrows are cut with an opening angle of 90° so that the snow layer under continuous movement is cut in two inclined intersecting planes. Cut stratum having a shape of an isosceles triangle in its cross-section is lifted to the surface of the site along the wall of the furrow and its laying is performed at the specified distance from the furrow. Humidification and compaction of faces of furrows with formation of structure of ice skeleton of snow-covered sheet by application to processed snow surface of vertically directed downward dynamic load, in the form of heat sealant from heat-conducting material, lowering into the made furrow, into hollow facets of which along the flexible hoses there supplied are exhaust gases and heated it. Additional heating is performed by means of nozzles in the form of burners. After compaction and heat treatment of surfaces of faces of furrows with a heat compactor, snow and clipped snow layer near the furrow are sealed statically by back ski of installation for formation of furrows for radar reflectors. Layer of metallized electroconductive composition is applied on side surfaces of the furrows. Furrows are filled with snow or ice.

EFFECT: enabling simulation of linear objects in low-temperature conditions, broader capabilities of producing radar reflectors in low-temperature conditions, high quality of radar reflectors and reduced time costs for their production.
