Mobile solid-state annular phased array radar for detection of low-flying targets "Rosa-M"

Назначение

The low-flying target detection radar (LFTDR) is designed for automatic detection, measurement of primary coordinates (azimuth, range) and speed of aerial platforms (AP), automatic tracking of APs in active and passive jamming conditions, output of radar information to a remote control system; automatic AP classification (fixed-wing aircraft, helicopter, cruise missile, balloon, unidentified target); determination of jammer bearings.

Достоинства

Design features

  • the LFTDR setup (tearing down) is assisted by hydro-mechanical devices;
  • the antenna system is an annular phased array;
  • digital pattern-forming (no mechanical antenna rotation), the LFTDR
  • scans the space in azimuth by 4 partial patterns whereby each pattern
  • performs linear scanning across 90˚ sector;
  • the transceiver device is solid-state, multichannel, modular.
