Low-flying and ground objects detection X-band radar "Rodnik"
Назначение
The radar is designed for detection, measurement of the coordinates and parameters of motion of low-altitude and ground-based platforms (azimuth, range, range rate), automatic target classification and tracking within the assigned zones, and output of radar information to a user according to the assigned protocol.Тактико-технические характеристики

Достоинства
Design features
- digital active phased array (PA) used as the antenna system;
- each transmitting element of the PA has its own transceiver unit a solid-state one with digital forming of the probing signal modulation law and double transformation of the received signal;
- space surveillance, detection of targets, measurement of the coordinates and recognition are automatic, without involvement of the operator;
- the radar is mounted on a unitized mobile hydro-mechanical platform installed on a special-type trailer chassis. The radar automated workstation is remote-located at the user’s command post.
