Introduction
The WaveGuide Onboard is a highly accurate wave and waterline monitoring system for
use on floating vessels. The system is robust, easy to install and explosion proof.
The WaveGuide Onboard includes two built-in sensors:
•A radar sensor that measures the distance to the water surface.
•An inertial measurement unit (IMU sensor) allows for motion compensation.
The WaveGuide radar is a low power X-band FMCW radar that measures the distance to
the water surface with an accuracy of < 1 [cm]. The IMU sensor measures acceleration and
hence requires a band-pass filter and a double integration cycle to obtain translation. The
position of the water surface is obtained by subtracting the calculated translation (IMU)
from the measured distance to the water surface (radar).
Filtering, integrating and aligning the raw data signals causes a 100 to 120 [sec] delay in
calculating resultant heave data. That in turn is further processed to provide wave height
parameters and wave spectra.
The measurements and calculated parameters are stored on the system and made available
to the user via a web-based interface or as a stream of UDP messages.
This manual describes the Explosion proof version of the WaveGuide Onboard system.
Please refer to the Radac website for all other manual versions.
Warning
Do not use the instrument for anything else than its intended purpose.
This manual consists of 4 chapters. Chapter 1 provides safety and security related informa-
tion. Chapter 2 specifies the WaveGuide radar positioning criteria for optimal measurement
quality and 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 for a list of measured and calculated parameters. And to
Appendix 2 for specifications, information about certification and environmental conditions
applicable to the WaveGuide Onboard system.

Chapter 2
Radar positioning and installation
2.1 Positioning
Figure 2.1: The 5◦[deg] half
top angle of the F08 antenna
beam and the reference level
for mounting height measure-
ment.
For obtaining the best results from a WaveGuide Onboard the
following radar positioning criteria must be taken into account:
•It is advised to choose a mounting position such that the
WaveGuide radar beam is free of large reflecting obstacles
(the beam of the F08 antenna has a 5◦[deg] half top angle
as shown in Fig. 2.1). The minimum horizontal distance
between the radar and any obstacle in the beam’s path
should be at least 10% of the vertical distance between
the radar and the obstacle. This does not only include
horizontal objects in the beam’s path but also vertical
structures.
•Any structure that the WaveGuide radar is mounted to
might have some influence on the wave flow around it.
Hence, it is advised to mount the radar at a position facing
the mean wave direction so that the radar can measure
the least disturbed water surface. In most cases the ship’s
bow provides the optimal mounting position but as each
vessel has a unique shape, it is the user’s responsibility
to carefully identify the best position for mounting the
WaveGuide radar.
•The reference level for the mounting height of the radar
is shown in Fig. 2.1.
•Figure 2.2, shows the polarization plane of the signal emit-
ted from the radar antenna. If the WaveGuide radar is
mounted close to a large vertical wall, then the radar
should be mounted such that the polarization plane is
parallel to the wall. That is to minimize the effect of the
wall on the propagation of the signal. Nevertheless, the
horizontal distance between the radar and the wall should
comply with the previous criteria.
•A vertically mounted radar (0◦[deg] tilt angle) results
in optimal performance. But if necessary the WaveGuide
radar can be mounted with a maximum tilt angle of 15◦
[deg] (tilted to face the direction away from the structure
it is mounted on).

antenna and its polarization
plane.

2.2 Installation
Figure 2.3: Optional mounting
plate for the WaveGuide radar
(Part no. WG-MP-EX).
To facilitate the mounting of the WaveGuide radar, an op-
tional mounting plate is available upon request (Part no.
WG-MP-EX). Figure 2.3 shows a sketch of the optional
mounting plate and its dimensions.
The mounting plate can be fixed to two horizontal beams
(Fig. 2.4). The length of the beams must take into account
the minimum horizontal distance between the WaveGuide
radar and any obstacles in the path of the radar signal (as
explained in the radar positioning criteria). Each beam must
have 2 holes either 200 or 270 [mm] apart depending on the
intended orientation of the mounting plate.
It is advised to mount the horizontal beams first. Then to
attach the mounting plate to the horizontal beams and fi-
nally to mount the WaveGuide radar to the mounting plate.
Mounting the radar is done by mounting the radar antenna
to the mounting plate and then mounting the radar housing
to the antenna.
Figure 2.4: Top view of the hori-
zontal mounting beams.
Radac can provide an optional dual-purpose wrench/spanner
(Part no. WG-EX-tool). One end of the wrench (Fig. 2.5)
is an open-end wrench that can be used to tighten the an-
tenna to the mounting plate. While the other end is a pin
wrench that can be used for tightening the radar housing to
the antenna. Upon request, Radac can supply an optional
frame (Part no. WG-MH-EX) that allows for mounting the
WaveGuide radar and mounting plate at angles 0, 5, 10,
15 and 20 [deg] away from vertical (see Fig.2.6). The radar
mounting plate (Part no. WG-MP-EX) is included with this
frame as well as brackets to allow mounting the frame to a
handrail.

that allows mounting of the
WaveGuide radar (Part no.
WG-EX-tool).

allows mounting of the Wave-
Guide radar at different angles

2.3 Cable
Figure 2.7: Block diagram of the
Waveguide Onboard system.
When selecting a cable for use with a WaveGuide system,
the following requirements must be used:
•Two wires for power transmission. The choice of power
supply will influence the diameter and insulation thick-
ness of those wires.
•Four wires for data transmission. The use of an
Ethernet data connection necessitates the use of four
twisted-pair wires (22-24 [AWG] and minimum insu-
lation thickness of 0.245 [mm]).
•The cable must be shielded and can have a maximum
length of 80 [m].
Upon request, Radac can supply an optional cable that com-
plies with the WaveGuide system requirements for power
and data transmission.
2.4 Gland
Depending on local regulations, this device can be connected by using glands, direct entry,
or conduits
An explosion proof (Ex-d) compound cable gland (M20), plus a M20 to 3/4" NPT converter
are supplied with each WaveGuide radar for use as a safe and watertight cable entry point.
The supplied gland allows the installation of cables from 6.5 to 11.9 [mm] in diameter.
Two approved 3/4" stopping plugs are provided for sealing the unused cable inlets
Note
Instructions supplied by the manufacturer for installing the included cable gland are
provided separately in its packaging.
Caution
The use of Ex-d certified materials of an inappropriate IP value or the improper
installation of cable glands, conduits or stopping plugs will invalidate the Ex approval of
the WaveGuide.
