Installing the Radar hardware

Overview

This section details the installation process, which comprises the following steps:

  1. Determine radar sensor locations
  2. Mount radar
  3. Connect radar sensor
  4. Prepare laptop
  5. Connect laptop
  6. Level radar sensor
  7. Confirm sensor coverage


CAUTION - Before performing any installation task ensure you are aware of Health & Safety procedures.

 

 

Preparing the laptop

IMPORTANT: Ensure that your laptop has its IP address set to operate within the same subnet as the radar sensor

Factory settings

The IP address (e.g. 192.168.0.1) of the radar sensor is preset before leaving Navtech Radar Limited according to client specifications and will be declared on a label attached to the outer casing.
The subnet mask of the radar sensor is often preset to 255.255.255.0 but could also be set wider (such as 255.255.0.0) if requested. Therefore, if the sensor IP address is 192.168.0.1 and the mask is 255.255.255.0, then your computer must use an IP address in the range: 192.168.0.2 to 192.168.0.254.

Changing factory settings

The IP address and subnet mask can be changed using firmware commands sent to the radar either via Telnet (see [5]), or using a serial connection (see [D3]).

Connecting your laptop

  1. At the radar, connect the laptop via CAT5 cable to the radar.

 

  1. Ensure that the radar sensor is powered on and is rotating - you can faintly hear the rotor when it is running.
  2. Use SPx Radar View application [1] to display the radar data. (See Annex A )

 

Levelling radar sensor

For optimum detection performance it is important that each sensor is level in relation to the area that it surveys. Level in this sense may not mean absolutely horizontal, generally the radar will be levelled so as to scan parallel to the boom they are to protect.
The exaggerated examples below show how a sensor with an incorrect incline could miss targets which are lower down the slope:

!worddave8ff5a3a9065f2d19c81ae8e5a897c26.png|height=295,width=294!A Digital Level as indicated in Figure 16, can be used to ensure the radar is installed level. This should be checked in two axes, on the radar lid, as shown below. The objective is to install the radar so that it scans in a plane which is parallel to the boom or structure which is being protected

      1. Adjusting radar



!worddav2356dd6b15e904369316b18a4a5c4411.png|height=309,width=521!RadarOnce installed on the machine, fine adjustments of the radar level may be needed. These are best made with reference to the actual radar image, as viewed in RadaView test software
h7. Figure 17SPx RadarView display (A)

Figure 18SPx RadarView display (B)


Using the RadarView application to view the radar data (see Annex A), you are aiming to have an equal amount of data either side of the radar.

  1. If there is more radar data one side than the other, as shown in Figure 17, change the angle of the radar until you have an equal amount of data either side of the radar, as shown in Figure 18. Radar targets can be used as the test object.
  2. If there is not enough radar image to view from objects/structures already within the radar line of sight, test targets can be used instead. Adjust the radar tilt of the radar on the threaded studs, to maximise the signal level on the 2 targets are determined from the RadarVew software (See Annex A for detailed instruction).

Figure 19Radar view to locate target

    1. Securing the radar
  1. Secure the radar on the mounting bracket, or post plate. To do this: lock off the two lower nuts on each stud by tightening one against the other. (This is to ensure that, if the radar is removed, the tilt angle is not changed)
  2. Record the tilt angle from the digital inclinometer. See Annex E for a sample table.

 

Confirming sensor coverage

  1. Install and configure the Witness software as described in [2].
  2. Enter basic detection areas into the Witness interface. (See [2]).
  3. Where possible, place test objects into the radar detection zone. Monitor these on the interface and confirm that detection alarms are raised
  4. Refine the radar detection zones, based on the tests and save the settings.
  5. Disconnect the laptop from the radar and connect the radar to the infrastructure network switch.
  6. Repeat for each radar

 

3. Health & Safety

General
        1. A first aid kit should be available at all times.

 

        1. In addition to the conditions detailed in this section the Site Safety Procedures for the location where the equipment is being installed must be complied with at all times.

Maintenance
        1. Make sure that electrical supplies are properly isolated before removing any covers. The supply should be disconnected by the operation of the main isolating switch, removal of fuses or other acceptable method. A notice should be placed at the point of isolation showing:-
DANGER - WORK IN PROGRESS

 

        1. Place a barrier or guard rail round the work area.

 

        1. When working on elevated equipment, make sure that all ladders and staging are secure. If necessary, wear a safety harness.
        2. Be aware of any special hazards specific to the site or location where equipment is located. Take all necessary precautions.




Annex AUsing SPx RadarView
The SPx RadarView application consists of two files which must be located in the same folder (any folder) on your laptop:

          • SPXRadarView.exe
          • SPXRadarView.rpi

 

  1. Run SPXRadarView.exe. You should see a blank main screen:

Note:In the lower panel, the Video and Turn indicators will be red indicating that

there is no communication with the sensor.

  1. Click the Channel-A menu on the toolbar, and select the Source... option.


Ensure that the Selection option is set to Network and in the Address field, enter the IP Address of the sensor. The Port must be set to 700.
Click OK.


!worddav3c0dd25e349f268d9479457b8c8e8b28.png|height=370,width=508!Once the IP address and port are correctly set and the application makes contact with the sensor, the Video and Turn indicators should turn green. Shortly afterwards, you should begin to see radar scan information within the main window.
On the left side of the screen, ensure that the Raw option is ticked.

  1. Click the button to show the Display Control dialog box:


Ensure that in the Raw Radar section, the Fading option is set to Sweep and the Rate (sweeps) is set to 5. Click OK.

  1. Click thebutton to zoom into the radar view so that you can clearly see the both of your test targets:

 

  1. Right click the mouse pointer on the exact middle point of one of the targets to display a popup options box. Click the option Popup Channel-A AScan…. to display a scan window.








Distance from radar m

Signal strength dB


The scan window provides live signal strength data concentrating only on the angular direction of the chosen target from the radar sensor. In each of the two graph plots, the x-axis shows the distance from the sensor while the y-axis indicates the returned signal strength. You should see a spike representing your target at the relevant distance.

  1. On the top graph, left click on either side of the spike to create a zoomed view on the lower graph.

This will allow you to see small changes in the returned signal strength on the lower graph when levelling the sensor:

  1. Repeat steps 5 and 6 for the other target so that you can view both on screen at the same time.
  2. Adjust the radar sensor level (See Section 2.7) while checking the scan graphs to ensure the best response from both targets.
  3. To assist with orientation, optionally click the button to show the Graphics Control dialog box:

Two options within this dialog box are of particular use:

  • Enable the Compass Ring option to superimpose compass graduation marks around the sensor view.
Note: North is aligned to the zero point of the radar sensor, not magnetic north.
  • Enable the Range Rings option to overlay range lines every 100m onto the sensor view

Annex H Installing in Harsh Environments

 

Chesterton© 740 Aerosol Application to I-Series Radar Connectors on Installation


When connecting data and power cables to radars in harsh or corrosive environments Navtech recommends the use of Chesterton© 740 as a product to protect the military specification connectors from corrosion.
This is a recommended best practice. Failure to apply the product could mean extra field time for engineers and the costs that this will incur.
Over extended periods of exposure to the sometimes harsh environments that radars are installed into the connectors can become corroded making their removal difficult, even causing damage to the radar in extreme cases.

Health & Safety


Care should be taken with solvent based aerosol sprays to avoid contact with the eyes or excessive inhalation of fumes. Especially in enclosed areas or poorly ventilated areas. Gloves and a mask and goggles should be worn.
A safety sheet is available for Chesterton© 740 at this weblink. – or visit www.chesterton.com and use the search facility to locate '740 rust guard'.

To apply Chesterton© 740 Aerosol product.

  1. Attach the power and data connectors to the radar. Checking their surfaces are free from dirt, oil, grease and moisture.

 

  1. If the radar has a vent plug attached temporarily cover or mask the vent so that when spraying the connectors no spray enters the vent plug.

 

  1. Evenly apply the spray to the connectors. Observing the Health and Safety guidelines while doing so.

 

  1. While drying residual product can be removed with a cloth. After drying a degreaser can be used to remove the product.

 

  1. Remove the temporary vent plug mask/cover to allow the plug to breathe.
