Updating of 1L13 Radar ("NEBO-SV")

123

 

Composition. Radar composition, depending on completeness arrangement includes up to 2 - 3 transport units.

Completeness:
 Cabin of antenna-rotary device (АPU);
 Hardware cabin (АP);
 Diesel power station with two power aggregates 20 KVA (DPS cabin).

By the customer"s request, the DPS can be installed on separate chassis.

Modernization of Survey Radar NEBO-SV is a new development of AEROTECHNIKA corporation, in which there are realized all of modern technical ideas and long-term experience of corporation activity:

• It is implemented complete coherence of the station, due to what radar parameters are considerably improved;
• It is applied wide range of narrow- and wideband soundings signals, and that enabled Radar adaptation to the different terms of combat operation;
• It is realized digital treatment of the reflected signals on intermediate-frequency, including the matched filtration, jamming suppression, targets detection and measuring of coordinates, generation of routes and delivery of information to consumers;
• Apply of our own software which is repeatedly tested in operation in the most different conditions, and has confirmed its high efficiency and reliability;
• It is used only COTS spare parts from the known suppliers, and that together with the certificated quality system has provided reliability of the station.

 

 General view of radar solid-state transmitter

 Remote workplace ARM-V can be moved off from hardware cabin to command post up to 1,200 m. Delivery of information from BCOS to ARM-V is carried out through modem channel.
