1. A radar-absorbing insert for personal body armor (PBE), characterized by being a modular combined insert consisting of two layers: the first layer is a radar-absorbing elastic plate of the KhV-2.0 brand, the second layer is a sheet paronite of the PON brand; the layers are bonded together with a polyurethane-based adhesive; while the radar-absorbing insert is designed to be installed in the pocket of the PBE module through a flap with a textile fastener.

Description

The invention relates to means for reducing the visibility of personal protective equipment (PPE) in the ultra-high-frequency range of radio waves from ground moving target reconnaissance radars (RMRR) and ensures a reduction in the level of radiation reflected from the PPE. Existing SIBs do not have the properties of reducing visibility in the ultra-high-frequency range of radio waves from radars, which, in connection with the active development and use of various types and means of technical reconnaissance, including the RNDC radar, requires the development and implementation of technical solutions and technologies for reducing their visibility in the design of serially produced SIBs. The visibility in the ultra-high-frequency radar range is reduced by using a radar-absorbing insert (1) (Fig. 1) in the composition of the SIB sample, characterized in that it is a modular combined insert of two layers: the first layer is a radar-absorbing elastic plate of the KhV-2.0 brand (2), the second layer is sheet paronite of the PON brand (3); the layers are glued together with polyurethane-based glue; wherein the radar-absorbing insert is designed with the possibility of installation in the pocket of the SIB module (chest (4) (Fig. 4) and back (6) (Fig. 5) sections) through a valve with a textile fastener ((5) (Fig. 4), (7) (Fig. 5)). The general view of the radio-absorbing insert is shown in Fig. 2 (front side) and Fig. 3 (back side). The placement of the radio-absorbing insert (1) in the pocket of the chest section of the bulletproof vest is shown in Fig. 6. A radar-absorbing insert is designed to reduce the power of the signal reflected from the radar back to the radar. It converts the energy of the electromagnetic field in the radio range into other forms of energy. When the electromagnetic field interacts with the insert, absorption, scattering, and interference of radio waves occur. Absorption weakens the incident wave field by converting electromagnetic energy into heat due to dielectric and magnetic losses and scattering in the material. Scattering and interference of radio waves is characterized by the reflectivity of the radar-absorbing materials used in the direction of the greatest secondary radiation from the surface of the protected object. The best technical result was demonstrated by a combination of a first layer of KhV-2.0 (2), directed toward the radar radiation, and a second layer of PON (3), directed toward the human body. Laboratory studies demonstrated a significant reduction in the S21 reflectivity modulus of the proposed radar-absorbing insert in the wavelength range from 0.8 cm to 4.5 cm. The proposed radar absorbing insert for the SIB has the following advantages: - low cost price; - low labor costs for manufacturing; - technological simplicity of production; - positive results of laboratory tests (significant reduction in the reflection coefficient modulus); - compliance with operational requirements for the SIB. The radar-absorbing insert for the SIB can be used to upgrade various types of commercially available SIBs to reduce their signature from RNDC radars. List of references 1. Yu.E. Donskov, V.G.
