“ROSA-Е” low-flying target detection radar system - Dream to live clean?

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt.

РосА

Designation
“Rosa” is designed for automatic detection and tracking of low-altitude aerial platforms and output of track information to an automated control system.
Composition:
- from 1 to 5 autonomous low-altitude target detection radar sets (LARS);
- remote control system;
- SPTA set.

Advantages:
- absence of moving parts due to use of a ring-shaped solid-state phased array;
- use of digital synthesis of the probing signal and digital processing of the received signal;
- effective detection of low-flying small-RCS aerial platforms;
- operator-free automatic operation;
- fully automatic functional check;
- high radar concealment and jamming immunity.
