Description: It is intended for air targets reconnaissance, two coordinate (range and azimuth) measurement and tracking with trace characteristics issuing, “friend-or-foe” interrogation of air objects – aircraft and howering helicopters, remote controlled vehicles and cruise missiles, including low-flying and extremely low-flying, on base of intensive reflections from the Earth surface, local objects and meteorological formations. Limits of operating characteristics are extended in comparison with P-19M radar.
