    "notes": "The 64N6 (NATO codename 'Tombstone') 3-D long-range surveillance radar comprises a hydraulically raised antenna assembly and radar shelter mounted on a common semi-trailer. The phased-array antenna set has a double-sided antenna aperture. Its 3-D performance is obtained by rotation of the antenna once every 12 seconds and electronically scanning the antenna beam, in both azimuth and elevation. Scan sector capability for detecting tactical ballistic missiles is also provided. This can detect aircraft and cruise missile type targets at a range of up to 300 km and ballistic missiles with launching ranges of up to 1,000 km using the sector scan facility. An IFF transponder subsystem is fitted. The radar is used for target detection and tracking in normal, clutter and severe ECM environments. The data obtained are relayed to the command post for processing and assessment. The radar can detect targets with speeds of up to 2,788 m/s (10,000 km/h). The export designation of the system is 83M6E. The S-300PMU-2 system designation is 83M6E2.\n\nThe Air Defense 64N6 (NATO code designation of Big Bird or Tombstone) is a mobile radar detection station with bilateral antenna, automatic control of modes and data, working in a centimetric range of frequencies. It is intended for maintenance with 54N6 radar-tracking information system and 83N6 control facilities for the S-300PM.\n\nThe 64N6 provides detection of the air targets with resolution, accuracy of definition of coordinates and rate of updating of the data, allowing tracking of targets, follow the trajectory without difficulty, and overcome active and passive countermeasures, definition of the state accessory(belonging) of the found out purposes, and also directions of active countermeasures.\n\nElectronic scanning by a beam of illuminators in azimuthal and elevation planes in a combination to fast switching the sides of radiation of illuminators and uniform electromechanical rotation of illuminators on an azimuth allows redistribution of radiated energy in separate directions and sectors of a zone of the review due to temporary expenses for the review of various sites of space depending on radar-tracking conditions, to divide(undresse) visibility range into a zone of the regular review and a zone of support, to optimize time allocation for air defense due to use of procedures of detection in a combination with a mode of selection of the moving target. Borders of action are established for height and range by operators or automatically.\n\nProtection against active countermeasures is provided with automatic reorganization of carrying frequency by results of the analysis of tracking conditions. For protection against the active countermeasures operating on lateral petals of the diagram of an orientation of antennae, the three-channel self-balancing potentiometer connected to compensatory aerials is used.\n\nProtection against passive countermeasures is made due to use of equipment SDTS. Temporary automatic adjustment of amplification is applied to reduce the quantity of false tracks in a near zone (up to 65 km) in the channel of detection, in a distant zone - the scheme of stabilization of a level of false alarms. To reduce the quantity of false returns from subjects on district and the inactive purposes it is applied intersurvey the signals received from same sites of space during several periods of the review.\n\nManagement of air defense work and devices entering into it, processing of the radar-tracking information and definition of coordinates of the purposes is carried out by a computer constructed on the basis of two specialized computers. The built in monitoring system checks functioning the equipment and defines malfunctions.\n\nThe structure of the command post includes means of speech communication, and also the broadband communication line 5?312 for transfer of the information on a radio channel or on a cable. It is completed by means of independent electrosupply into which structure enters the unit producing the electric power of a three-phase alternating current by frequency of 400 Hz by a voltage of 220 Volts given means of external power supplies can be used the converting device and diesel power station.\n\nEquipment is placed in two containers F6 (the illuminators, transmitting and reception devices and devices for processings of information and management), installed on the lorry convoy tractor MAZ-74106. The system is served by fighting calculation from 4 person. Its weight is 60 tons",
