ЗАСТОСУВАННЯ НАПІВАКТИВНИХ РАДІОЛОКАЦІЙНИХ СИСТЕМ (У ПОЛІ ПІДСВІЧУВАННЯ СТОРОННІХ ДЖЕРЕЛ) ДЛЯ ВИКОНАННЯ ЗАВДАНЬ РОЗВІДКИ ПОВІТРЯНОГО ПРОСТОРУ

The article deals with the possibility of using signals of the Internet coverage, cell-phone networks, radio and television signals to provide detection of air targets. The advantages, disadvantages, composition and principle of operation of a semi-active radar system are considered in this article. Issues of technical realization of antennas and receivers of a semi-active radar system are investigated. An algorithm for signal processing in a semi-active radar system is proposed. For fulfilling the tasks of air surveillance and timely alerting of the air defense system to a higher degree of readiness when detecting the air threats and airborne intelligence assets of the enemy, currently in the area of the Operation of the Joint Forces the radar air surveillance system is deployed. This system is made up of traditional active radiolocation tools. The main disadvantage of such a system is its low survivability, which is due to the radiated signals, and, consequently, the ease of reconnaissance of radar positions by the enemy. Preservation of radar air surveillance system positions undetected and, consequently, the survivability of those radar systems is possible by supplementing them with the means of semi-active radar. Also, in the context of the so-called hybrid war in the area of Operation of the Joint Forces a ramified system of radio equipment continues to operate that can provide illumination field.
