The principles of constru.ction and implementation of semi-active radar systems, using the illumination from third-party sources are presented. The results of theoretical and experimental researches of the Saint-Petersburg state electrotechnical university "LETI" n. a. V. I. Ulyanov (Lenin) and JSC Β«SRI "Vector"Β» in this direction are given. The advantages of semi-active radar systems, the possibility of coherent processing with a large accumulation time in com.bination with the digital formation of the directional diagrams of the receiving antenna arrays, as well as prospects of application systems semi-active radar for the protection of important sites and monitoring areas, including the detection and orbital support of ground, surface and aerial objects.
