摘要：At present, optical and optoelectronic reconnaissance means are widely used in the armed forces of the leading countries of the world to detect and recognize land, air and sea objects, as well as to deliver strikes at night and in adverse weather conditions. The basis of such means is the airborne reconnaissance and strike optical and optoelectronic systems, which include: optical devices for direct observation; aviation cameras, including optoelectronic; forward looking television stations; television cameras; optical-electronic navigation and sighting systems. This equipment allows conducting aerial visual optical, photographic and optical-electronic (television) reconnaissance in the daytime and at night. Recently, much attention has been paid to the issues of reducing the visibility of objects in the visible wavelength range due to the use of passive cloaking means. Various directions of creation of these means, as well as methods of reducing the effectiveness of the use of systems for detecting and destroying objects in the visible range of wavelengths, are considered. However, little attention has been paid to assessing the effectiveness of the use of passive camouflage means to protect objects in a real situation, and no mathematical apparatus has been developed for these purposes. Therefore, there is a need to increase attention to the development and use of the latest camouflage means, as well as to assess their ability to reduce the visibility of important military objects, weapons and military equipment. This requires further research, aimed primarily at developing the theory and practice of assessing the use of camouflage means and developing practical recommendations for protecting objects. The article evaluates the capabilities of opticalvisual reconnaissance equipment installed on space, aviation and ground vehicles for object recognition. The initial data on objects and conditions of exploration required for calculations are given. Analytical expressions are obtained for calculating the signal-to-noise ratio of images of the original and masked objects and their shadows, the probabilities of detecting the original and masked objects. A mathematical apparatus has been developed for evaluating the effectiveness of masking measures in the visible wavelength range. The results obtained can be used in the development of new concealment means, as well as in the assessment of existing and prospective reconnaissance means in the visible wavelength range.
其他摘要：Проведено оцінку можливостей апаратури оптико-візуальної розвідки, яка встановлена на космічних, літальних апаратах та наземних засобах щодо виявлення об’єктів. Наведені необхідні для розрахунків вихідні дані по об’єктах та умовах ведення розвідки. Отримано аналітичні вирази для розрахунку відношення сигналу до шуму зображень вихідного й замаскованого об’єктів та їх тіней, ймовірностей виявлення вихідного й замаскованого об’єкту. Розроблено математичний апарат для оцінки ефективності заходів маскування у видимому діапазоні довжин хвиль. Отримані результати можуть використовуватись при розробці нових засобів маскування та оцінці існуючих та перспективних засобів розвідки у видимому діапазоні довжин хвиль.
