CEROS 200 can be used to control long-range surface-to-air missiles (for the first time in a 9LV system), for medium-range
engagements with guns or for the control of CIWS. The two-axis pedestal has an angular speed of 2 rad/s and is approximately
2 m high, 1.6 m in diameter and weighs 700 to 800 kg. The prime sensor is a tracking Ku-band (J-band) radar with stabilised
cassegrain, monopulse antenna and grid-pulsed helix travelling wave tube transmitter with a peak power of 1.5 kW which
operates in the 15.5 to 17.5 GHz frequency range and produces a 1.5~ wide beam with 41 dB gain. There is a three-channel
amplitude monopulse receiver with 0.2 Ás compressed noise width and a noise figure of 10 dB.
More than 100 frequencies are available permitting the combination of pulse Doppler-MTI operation with batch-to-batch
frequency agility, a typical processing batch involves four MTI pulses and 32 pulse Doppler pulses. Pulse-to-pulse frequency
agility is retained for use when return suppression is not required. The CelsiusTech High Accuracy Sea Skimming Estimator
(CHASE) signal algorithm may be added to enable missiles operating at 6 to 50 m above the sea to be tracked without
multipath interference.
The CWI version (which was selected by Australia, Denmark and New Zealand) has an additional X-band or I/J-band (8 to
12 GHz) channel which generates a high-gain pencil beam. Focusing of the two bands is achieved through a combination of
frequency selective surfaces in the main- and sub-reflectors as well as the provision of another X-band horn to provide a wide
`null-filling' beam for the missile's rear reference.
