Description: The article assesses the capabilities of weapons and military equipment reconnaissance with modern means of detection with side-scan radar stations, which are used on space and aerial reconnaissance vehicles. The initial data necessary for calculations on the objects of weapons and military equipment, depending on the conditions of conducting reconnaissance , are given. To reduce the visibility of objects, modern scattering and absorbing coatings are considered. They make it possible to reduce the radar and radio-thermal visibility of weapons and military equipment when the enemy uses modern and promising means of detection and weapons. Analytical expressions are obtained for calculating the signal-to-noise ratio, which is perceived by the operator's eye on the radar image. Expressions were obtained for calculating the effectiveness of reducing the radar visibility of objects when they are protected by scattering and absorbing coatings. A mathematical apparatus for evaluating the effectiveness of reducing the radar visibility of objects by using scattering and absorbing coatings is developed. The above calculations allow us to conclude that a single-layer scattering and absorbing coating reduces the equivalent scattering area of an object of complex shape by an order of magnitude over the entire range and angles of irradiation. A two-layer coating reduces the equivalent scattering area of such an object by two orders of magnitude in the range of the radar stations of the lateral survey of the reconnaissance/strike system.


Keywords: scattering and absorbing coatings, radar and radio-thermal visibility, the radar stations of the lateral survey
