Introduction

This section provides an explanation on how to add radar sensors through the Create or Discover New Radar wizard, and the different mode options it presents.

Within the ClearWay™ application, the radar represents both the radar and the software tracker which together provide the core capability of the system. Once these components are configured correctly the system will be able to accurately detect, classify and track targets on the designated highways.

Open Create or Discover New Radar Wizard

Once you have configured the site, there will be a Default Radar Group created, ready to be edited. To add new radar to the site configuration you will need to open the Create or Discover New Radar wizard:

  1. Ensure Config Function is enabled.

  2. In the Configuration Tree, select the appropriate Radar Group folder into which you want to add the new radar.

  3. From the Configuration Panel (by default on the right hand side of the screen), select New.

  4. The wizard will now start:

Mode Options

You will next need to select a mode.

Basic Mode: This mode requires manual input of the values:

Auto Discover: This mode automatically adds radar by discovery through a discovery message sent by the radar through the network, using multicast. These messages are detected by the track engine and reported to the Witness 4.0 software. In order for this mode to work, radars must be physically installed, powered on and connected to the network.

If the radar is in secure mode, discovery broadcast is disabled.

Import from File: This mode gives you the opportunity to insert a radar group via Excel Spreadsheet saved as a Comma Separated Values file.

After you choose Import from File from the top dropdown, fill out the other dropdowns before clicking Next. The 'browse files' window will then pop up, and you can select your .csv.

Your desired radar configuration should be set out like this:

This method is a reliable option if large groups of radar are being installed, as there is no limit to the number of radar that can be tabled in Excel. The results will appear in a Radar Details display screen, similar to the one above, for you to review.

Other Radar Settings

Layer: Select the display layer onto which you want to create the radar. Layers

Distance Between Radars: This is the default spacing distance between radar used to automatically position the radar when you select more than 1 radar. The first radar (or only radar if creating one) will be positioned in the centre of the PPI display. The wizard assumes you have started the process with the display approximately in the correct position for the new radar. You can move the radar's position once the wizard is complete.

Model: The model of the radar you are adding. All new Witness installations should be using the CTS-350X.

Radars to Add: The total number of radars you wish to install.

Connection: The connection type and appropriate network settings:

Local - This means the tracking software will be running on a PC or server. managed by the Track Engine service. Typically this means the tracking software is centralised and has to make high bandwidth connection from the server to the sensor to consume raw radar data. You only need to provide the radar details for this type of connection. When using local trackers the PC / server must be powerful enough to run a tracker for each radar it is managing. This connection type is also used for playing back radar data recordings.

Remote - This means the tracking software is running on a remote EPU (Edge Processing Unit). The EPU is a small embedded single board computer which is usually located with or close to the radar. The EPU makes a high bandwidth connection to the radar to consume raw data but uses a low bandwidth connection to the rest of the software. You need to provide the radar details and the EPU for this type of connection.

On-Board - This means the tracking software is running on the radar sensor. This feature is only available on the CTS-350X radar, version 4 or newer. In this setup the high bandwidth connection is inside the radar and the link from the radar to the rest of the software is a low bandwidth connection. You only need to provide the radar details for this type of connection.

  1. On the second page of the Wizard it will be possible to configure each of the radars Addresses and Port settings.

  2. Once each radar has been updated, select Finish.

  3. The radars will now be created, saved to the configuration and added to the PPI display. Depending on how many have been created this may take a few seconds. Once complete, each radar can be selected, edited and re-positioned if required. In addition, all the advanced options are now available for configuration.
