METHOD TO REDUCE REVERSE RADIOLOCATING REFLECTION AND DEVICE FOR ITS REALISATION Russian patent published in 2012 - IPC H01Q19/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, namely, to methods to reduce the efficient scattering surface of objects (hereinafter referred to as ESS) during their radiation with a radio locator, and may be used to develop anti-radiolocating coats, materials and devices that reduce radio visibility of vehicles and other objects without variation of their geometric shape. The method to reduce reverse radiolocating reflection includes measurement of a diagram of reverse scattering of an object at the single-position radiolocation, application of elements onto a carrier, every of which may cause diffraction of a radiolocating wave, and placement of elements on an electroconductive radio-non-transparent surface of an object in compliance with measurement of their reflecting properties. The object is radiated with a coherent beam of quasi-plane radio waves with amplitude-phase space distribution of a diagram of reverse scattering of an object corresponding to the values of the measured field, at its single-position radiolocation, the structure of the electromagnetic field is registered near or on the surface of the object, and the registered structure of the field is reproduced on a carrier with the help of elements capable of causing diffraction of a radiolocating wave, in the form of a radio hologram. The device to realise such method comprises a carrier from a dielectric radiolucent material and elements causing diffraction of a radiolocating wave, fixed on a carrier and following the structure of the electromagnetic field with dimensions and location. The carrier is made of flexible material in the form of a scan of the object surface, and fixation of elements and reflection of the structure on the carrier are realised in compliance with amplitude-phase space distribution of electromagnetic field registered on the surface of the object or near it when the object is radiated with a coherent beam of quasi-plane radio waves with amplitude-phase space distribution complying with values of the measured field of the reverse scattering diagram at the single-position radiolocation.

EFFECT: invention provides for the possibility of reduction of reverse radiolocating reflection of objects of any shape in a wider range of angles of radiolocating radiation.
