    Positioning For obtaining the best results from a WaveGuide Height & Tide the following radar positioning criteria must be taken into ac- count: • 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 can be approximated to a conical shape having a 5 [deg] half top angle as shown...

  • Page 17 By default, during startup the WaveGuide system tries to obtain an IPV4 address by searching the Local-Area-Network for a DHCP server. If a DHCP server is available and the WaveGuide sensor completes the startup process, its IPV4 address can be found using a Zeroconf browser such as Avahi or Bonjour. If a DHCP server is not available, a temporary fixed IPV4 address can be set by connecting the two reset poles in the sensors terminal compartment for 0.5 to 2 seconds.

    Step 3. Configuration The configuration page contains five sections as listed in Table 3.2. Link Description Date&Time For viewing and setting the system time. Network For viewing and changing the network settings. Sensor For viewing and changing the sensor specific settings and for view- ing reflection diagrams.

    Step 3.2: Adjust network settings Figure 3.4: Adjusting the network settings. The network settings can be modified via the web-interface (Fig. 3.4). It is advised to use the default setting, to automatically obtain the network settings from a DHCP server, and assure from the side of the DHCP server that the system will receive the same IP-address at all times.

The mounting height is defined as the height of a radar above the reference water level in [m]. The reference point for measuring the height of each radar is the lower-side of the radar mounting flange (as shown in Fig.

The reflection diagram provides a useful insight in the quality of the reflection signal that is obtained by the radar. After changing the sensor parameters for the radar, rebooting the system is required for the changes to take effect.

    Step 4. Perform system check This section explains how to inspect the quality of measurements after configuring and rebooting the WaveGuide system (the start-up process can take up to 5 minutes). Step 4.1: Check system information page The system information table can be reached through the status menu item on the top-right of the web interface.

    Step 4.2: Check reflection diagrams The reflection diagram for each sensor can be accessed via the sensor configuration page by clicking on the corresponding "reflection" button (Fig. 3.7). A reflection diagram is a graphic representation of a 25 [ms] scan, where the signal strength [dB] is plotted against the measurement distance [m].

    Default message format The Default format starts a new line for each parameter in the subscription. The time used in the Radac format is Unix Epoch time in milliseconds (UTC time in milliseconds since 00:00:00 on the 1 of January 1970). Each line in the Default format ends with a Line-Feed character (char10).
  • Page 26 For a regular message the status character is a space. If an error occurs the status character becomes a letter A. An example of the output strings in the RWS format is, +0001 - 0004 A+9999 Format02 message format Modifications can be made upon request. For example, the Format02 the Korean Meteoro- logical Administration (KMA format) preferred a readable time format in the Korean time zone.
