CEROS 200 Fire Control Radar explained

CEROS 200
Type:	Fire-Control
Frequency:	ku band

CEROS 200 (CElsius tech Radar and Optronic Site) is a radar and optronic tracking fire control director designed by Saab for use along with the 9LV Naval Fire Control System on naval ships. When interfaced to modern missile or gun systems it provides defence against any modern threat including advanced sea skimming missiles or asymmetric surface threats in littoral environments.^[1]

Features

The radar design incorporates many electronic counter-countermeasures:

• Very low antenna side lobes
• Very wide bandwidth
• A large number of transmit frequencies
• Random selection of frequency
• Lock on jam, track on jam

Unlike other fire control radars, the CEROS 200 can guide 2 missiles, like the ESSM, at once.^[2]

Accuracy

The CEROS 200 director provides 3D tracking. This enables the operator to deal with advanced air and surface threats.

FCS firing accuracy as measured by an independent agency in a range of conditions:^[3]

Within 1 meter (radius): 36%

1–2 meter (radius): 23%

2–4 meter (radius): 19%

4–6 meter (radius): 22%
