  • Page 8: Anatomy Of Weather Radar

    1.2. Anatomy of Weather Radar Radome Sub reflector Antenna 70km Receiver Transmitter Antenna: The main purpose of the antenna is to focus the transmitted power into a small pencil beam and also to receive and collect the returned signal. Radome: Protects the antenna from high winds, dusts, and rain.

  • Page 9: Mechanical Operation

    The single X-band weather radar can be difficult to avoid problems with blind areas due to buildings, mountains or strong signal extinction by heavy rain. Furuno provide multi-radar system that consists of three radar systems. While two radar systems are detecting and tracking rain clouds and observing their movements, the other one is working as RHI sector scan mode at high speed and cutting through the clouds to observe their internal structures.

  • Page 10: Side Lobe

    FURUNO radar Conventional radar Figure 1.4: Image of using 3 radars Figure 1.3: FURUNO radar detects cumulonimbus cloud faster than conventional radar 1.5. Side Lobe The energy radiated from an antenna forms a field having a definite radiation pattern. A radiation pattern is a way of plotting the radiated energy from an antenna.
  • Page 11 Front-to-Back Ratio: The front-to-back ratio of an antenna is the Beam width proportion of energy radiated in the principal direction of radiation to the energy radiated in Main lobe the opposite direction. A high front-to-back ratio is desirable because this means that a Side lobe minimum amount of energy is radiated in the undesired direction.

Location of Radar Installation 1) Confirm the observed region in relation the topography features: In this example the radar must cover an altitude of 1500 meters maximum and a 70km distance radius within the rainfall forecast area.

  • Page 13: Radar System Certificate

    4) Survey antenna surroundings: Ensure no interference to any surrounding antenna (e.g.: Broadcast, mobile (cell) phone station, radio, BS/CS, etc.) and no obstacles should be around the antenna. Moreover, secure a service space of 1 m or more around the antenna. In addition, strong reflections can damage the receiver if there are obstacles nearby.

  • Page 14: Requirement Of Calibration

    1.8. Requirement of Calibration Calibration is the activity of checking or measuring and comparing with a specific standard reference instrument. It may also include adjustment of the system to bring it into alignment with the standard. 1.9. Peripheral Devices External HDD (Hard Disk Drive): Useful for saving large amounts of data. Use USB3.0 device type to transfer the data at high speed.

  • Page 42: Azimuth Initial Setting

    5. AZIMUTH INITIAL SETTING Before or after execute the “Renew A-threshold” on section 4.4.3, the radar must adjust the azimuth offset. The radar orientation and actual geographical azimuth are normally different causing an incorrect initial echo indication. An azimuth adjustment is required for proper echo orientation. The order of adjust the highest accuracy of azimuth is as follows: 1) Solar position simulator on section 5.3.

  • Page 43: Echo (Clutter)

    5.2. Echo (Clutter) Use a topographic map w/ terrain to find out the location where install the radar from web site (It is not necessary if a map is already installed in the RainMap) to adjust the azimuth compare with the RainMap echo of radar.

  • Page 44: Solar Position Simulator

    Before After Figure 5.1: Image of azimuth adjustment Note: Some location will be difficult to adjust an azimuth from map if none of the mountain or any ground clutter is surrounding within 70km. But there might have a solution for example, if it is in a flat country like Denmark, a water tower in Lund, and Sweden, it used -1 degree, 10 km range and was able to detect coastline and the city boarders of Copenhagen.

    A.4. Modification Plan As shown in Table A. the current condition is not enough to protect the weather radar. It would propose the following modification plan to protect the weather radar. A.4.1. Extend existing lightning rod It installed a new lightning rod to protect the radar, but it is insufficient due to some restrictions.

  • Page 63: Add Extra Lightning Rod

    A.4.2. Add extra lightning rod This is an example of adding a lightning rod to compensate for existing lightning rod limitations: It is installed next to a chimney, 8 meters away from the radar. In this case the chimney is fixed, therefore it is better to install a new lightning rod as shown in Figure A.4.

  • Page 65: New Standard Lightning And Angle Of Protection

    A.5.2. New standard lightning and angle of protection Lightning rod height and protection efficiencies were revised when IEC standards were renewed in 2003, replacing the older 1990 standard. The angle of protection decreases as the height of protected structure gets higher. Any protection level of structure over 60 meters will not be enacted in the protection angle because a lightning rod is ineffective for buildings over 60 meters when a side-on lighting strike hits side of a building.

  • Page 66: Communication Network

    COMMUNICATION NETWORK Radar needs an internet connection to provide remote maintenance service, main operation, and transfer of collected observation data. Recommendation of using network is the fiber optical or any faster network for transferring the weather observation data to the data center server or office. If the radar location does not have access to any fast network (up/download minimum 8 Mbps constantly) but can connect to a wireless network then use the internet just for remote operation and save the data to an external HDD.
