GENERAL DESCRIPTION
IN TRO DUC TION
1 The SharpEye
TM
Radar combines the latest concepts, technologies and state of the art
performance in surface search capability into a high reliability product for the maritime
industry. Comprising an antenna, gearbox and compact transceiver, SharpEye
TM
Radar
provides the mariner with a range of highly sophisticated and flexible operating modes and an
unsurpassed ability to detect small targets such as buoys, yachts and personal water craft, in
moderate to severe clutter environments. SharpEye
TM
radically departs from conventional
marine navigation radar practice through the transmission of low power RF pulses and
application of pulse compression and coherent pulse Doppler techniques to provide sub-clutter
visibility of targets.
2 The SharpEye
TM
Radar is available as an X-band Transceiver in upmast configuration
(DTX-A3) and is used with the Low Profile Antenna (LPA-A25).
3 The SharpEye
TM
Transceiver operates at fixed antenna rotation speeds of 22 RPM or
44 RPM for optimum update rate. The antenna rotation speed is preset during installation
and is not selectable by the operator.
4 The SharpEye
TM
Transceiver has a range cell size of between 15 m and 30 m, depending
on the range selected from the display.
5 Radar control is via a CAN bus to the display system with discrete analogue video, sync,
azimuth and heading line signals to the display.
6 The SharpEye
TM
Transceiver requires 110 V/220 V single phase AC for the transceiver
electronics and 3-phase AC from a Drive Control Unit (GTX-A24) for the antenna
turning motor. The Drive Control Unit uses the 220 V ship's single phase mains to generate a
variable frequency 3-phase output for the antenna turning motor. The frequency of the 3-phase
output determines the antenna rotation speed, and is set by links on installation to provide a 25 Hz
output for 22 RPM operation or a 50 Hz output for 44 RPM operation, provided the input
frequency is 50 Hz. If a 60 Hz input frequency is used the Drive Control Unit must also be
reprogrammed as described in Chapter 5 to provide the correct output frequency.
7 A transformer can be supplied to allow the Drive Control Unit to be used with 110 V
mains supplies.
8 The Upmast configuration is shown in Figure 1, and a typical implementation in Figure 2.
