Surface Movement and Perimeter protection Radar

The ELR 55303 is a Doppler radar with mechanical scanning of the antenna beam and pulse compression. Radar is designed for

  • Detection of slow moving objects on the earth or sea surface,
  • Detection of low-flying small-sized aircraft,
  • Determination of target coordinates (azimuth and range), EPR, radial velocity and Doppler spectrum width,
  • Selection and recognition of targets,
  • Terrain mapping
