DC POWER REQUIREMENTS
DC input
+24VDC
DC range: +19.5VDC to 30VDC measured at the unit under maximum load
conditions
DC power cable
Standard systems use 10 metre DC power cables.
If additional DC cabling is required, the cable must be of a sufficient gauge
to ensure that the minimum voltage required by the SCV/ SxV is maintained
under the worst case load conditions.
The cable must designed to ensure that the voltage drop along the cable
never causes the DC supply measured at the SCV/ SxV power connector to
fall below +19.5VDC under maximum load conditions.
For cable runs longer than 10m, Kelvin Hughes recommend a DC supply of
at least +28VDC and/ or a cable and DC supply that supports sensing lines.

to 9.38Ghz in steps of 0.02GHz
Frequency
Bandwidth
20MHz
PRF
1 – 4.5KHz depending on mode
Processing
Pulse compression and coherent Doppler processing
Peak RF power
Measured at the output
of the SharpEye™ prior
to the antenna
High power
Low Power
50 to 80W (typical)
47 to 50dBm
(in normal operation)
12W (typical)
39.5 to 42.5dBm
ERP
(Effective Radiated
Power)
Peak radiated power (ERP) = 42dBW
Mean radiated power (ERP) = 33dBW
Pulse duty cycle
13% maximum (hardware limited)
Range scales
6, 12, 24Nm

Three mute (blanking) and one True.
ANTENNA
Size
530mm horizontally polarised planar array
Beamwidth
20 to 22° vertical, < 3.9° azimuth
Note: Due to the beamwidth of the antenna, target detection will be significantly reduced if the
SCV/ SxV assembly is tilted by more than 10° from horizontal/ flat.
Tilt
No tilt
0° with respect to mounting points (horizontal)
Gain
20 – 22dBi
Rotation speed
12RPM or 24RPM dependent of range scale and software installed.
