RADAC WaveGuide 5 Direction Onboard 2, Руководство пользователя

Страница: 5 / 40

Introduction
The principle of operation of a WaveGuide 5 Direction-OnBoard 2 is based on the syn-
chronized measurements of sea elevation (heave) at three di
ff erent spots on the surface of
the water. Using these measured elevations, and while taking into account the motion of
the sensors, the water surface slopes are calculated relative to two perpendicular horizontal
axis. Then the correlations between the calculated slopes and the measured heave values
are used to determine the wave characteristics and directional information.
The three WaveGuide sensors are composed of 2 WaveGuide Waterlevel sensors and one
WaveGuide OnBoard 2 sensor. The sensors communicate their data to a processing unit.
All three sensor measure the distance to the water surface and the OnBoard 2 sensor
measures the motion of the system. The processing unit takes care of the data handling
(synchronizing measurement, processing, distribution and presentation). The processing
unit also facilitates commissioning and (remote) servicing of the system. All facilities are
accessible via the built in web-server that runs on the processing unit.
The WaveGuide sensors are low power X-band FMCW radars that measure the distance
between the water surface and their antennas with an accuracy of < 1 [cm].
The WaveGuide sensors are available in two versions:
• The Explosion proof version, where the electronics are build into an explosion proof
housing.
• The Compact version, where the antenna and electronics are built into a compact
stainless steel housing. The antenna and electronics are the same in both versions
but the stainless steel version is easier to handle due to its compact size.
This manual describes the Compact version of the WaveGuide 5 Direction-OnBoard 2.
Please refer to the radac website for all other manuals.
Warning
Do not use the instrument for anything else than its intended purpose.
This manual consists of 4 chapters. Chapter 1 specifies the criteria of sensor positioning
for optimal quality of measurements. Chapter 2 illustrates the mounting and installation
procedure. Chapter 3 describes the commissioning of the system via the user interface.
Chapter 4 explains data processing, data presentation and data distribution.
Please refer to Appendix 1: System parameters for a list of measured and calculated pa-
rameters. Refer to Appendix 2: System specifications for specifications, information about
certification and environmental conditions applicable to the WaveGuide Direction-OnBoard
2. For information on the LED blinking modes please refer to Appendix 3: LED blinking
modes.
