MR-310 “Angara-A” (Cyrillic: МР-310 «Ангара-А», NATO-designator: Head Net A) is operating in the L-Band 3D air and surface surveillance and acquisition radar. It is a two-channel system with diametrically opposed antennas. The deflection of the electron beam on the PPI-display was also diametrical. One of the antennas is inclined, so that an elevation angle could be displayed with the help of the V-Beam method. The deviation from the 180° or the 0° is the measure for the elevation angle.
The radar was developed in the mid-1960s.
MR-300 „Angara” (Cyrillic: МР-300 «Ангара», NATO-designator: Head Net) is the 2D version of this radar, without the V-Beam slant.
