P-19 “Danube” (Russian designation: 1RL134; NATO designation “Flat Face B”) is a mobile two-coordinate radar station of the decimeter wave range. The P-19 radar can interface with all types of automatic interacting and control systems: P-18, SA-3 “Goa” and SA-2 “Guideline” surface-to-air missile systems, and PRW-9 und PRW-16 radio altimeters. The power supply of the station equipment can be carried out from electric generator 1, electric generator 2 and from external network 220 V ±5% 400 Hz. Power consumption does not exceed 15 kW.
The antenna uses horizontal polarization. The radar covering area in the vertical plane is determined by the antenna supply mode. In in-phase mode, the lower lobe of the visibility area is most extended and pressed to the ground. This mode is used to detect distant and low-flying targets. For targets with high flight altitude there may be omissions due to the multi-blade character of the radar covering area. In antiphase mode, the lobes are raised, which allows you to detect targets at a high altitude. The upper boundary of the detection zone in antiphase is 20°.
The station includes:
- A car with a K-4 body on a ZIL-131 vehicle, which houses: radar equipment, interfacing equipment with other radars, ground radar interrogator (1L23-6), data acquisition and transmission equipment, and a set of measuring equipment, internal telephone and radio communications equipment.
- The antenna-mast unit is mounted on a ZIL-131 vehicle, the platform on which there are two gasoline electric generators AB-16-T/230/4-400-M1 and an antenna rotation mechanism.
The radar can be combined with antenna-mast devices (AMU, kyrill.: Антенно-Мачтовы Устройство, АМУ) 1RL82, 1RL82М and 1RL82M1 to extend the operating range. The remote plan position indicator (VIKO) is connected to the radar by cables and can be located at a distance of up to 300 m from the radar.
