  • Page 33: Adjusting The Sensitivity

    1.12 Adjusting the Sensitivity The GAIN control is used to adjust the sensitivity of the receiver, and thus the intensity of echoes as they appear on the screen. It should be adjusted so that speckled background noise is just visible on the screen. To become acquainted with the way the GAIN control works, try rotating it between fully counterclockwise and clockwise positions while observing the radar picture.
  • Page 34 Press the A/C AUTO key. Use of a function key is also a good method for reducing sea clutter. For this purpose, presetting is required. Consult a FURUNO representative. CAUTION The auto A/C function can erase weak target echoes. Manual anti-clutter control From the fully counterclockwise position, slowly turn the A/C SEA control clockwise.

  • Page 35: Suppressing Precipitation Clutter

    1.14 Suppressing Precipitation Clutter In adverse weather conditions, clouds, rain or snow produce a lot of spray-like spurious echoes and impairs target detection over a long distance. This situation can be improved by using a function key provided that it is so programmed. If the function key fails to offer a favorable suppression of the rain clutter, adjust the A/C RAIN control on the front control head.

  • Page 38: Measuring The Bearing

    1.17 Measuring the Bearing Use the Electronic Bearing Lines (EBLs) to take bearings of a target. There are two EBLs, No. 1 and No. 2, which are toggled by successive presses of the EBL ON key. Each EBL is a straight dashed line extending out from the own ship position up to the circumference of the radar picture.

  • Page 39: Collision Assessment By Offset Ebl

    1.18 Collision Assessment by Offset EBL The origin of the EBL can be placed anywhere with the trackball to enable measurement of range and bearing between any targets. This function is also useful for assessment of the potential risk of collision. To assess possibility of collision: 1.

  • Page 40: Measuring Range And Bearing Between Two Targets

    1.19 Measuring Range and Bearing Between Two Targets Press the EBL OFFSET key, and place the origin of No. 1 EBL, for example, on a target of interest (target 1 in the illustrated example) by operating the trackball. Turn the EBL control until the EBL passes through another target of interest (target 2). Turn the VRM control until the range marker aligns with target 2.
  • Page 41 The zone has a fixed width of 0.5 nm in the radial direction (depth) and is adjustable only within 3.0 to 6.0 nm from own ship. On the R-type, the outer and inner boundaries can be set at any distance. On any radar type, the sector of the zone can be set anywhere between 0 and 360 degrees in any direction.

  • Page 42: Off-Centering

    Deactivating guard alarm Hold the [2] key depressed for at least 5 seconds on the FUNCTION 1 menu. In the IMO type, deactivation of TAZ 1 deactivates TAZ 2. TAZ 1 and 2 work independent in the Regular type. Note: The echo watch alarm is given to targets having a certain level of echo strength. This level does not always imply a landmass, reef, ships or other surface objects but can mean returns from the sea surface or precipitation.

  • Page 43: Echo Stretch

    1.22 Echo Stretch On long ranges target echoes tend to shrink in the bearing direction, making them difficult to see. On short and medium ranges such as 1.5, 3 and 6 nm scales, the same size targets get smaller on screen as they approach the own ship. These are due to the inherent property of the radiation pattern of the antenna.

  • Page 44: Echo Averaging

    ES OFF ES1 - Enlarged in bearing direction Use on range 1.5-12 Notes: 1) If the 1.5 nm range is preset with a pulselength of S1 or S2, and the 3 nm scale with S2, the echo stretch is not available on these range scales. 2) The echo stretch magnifies not only small target pips but also returns (clutter) from sea surface, rain and radar interference.

  • Page 105: Criteria For Selecting Targets For Tracking

    2.18 Criteria for Selecting Targets for Tracking The FURUNO ARPA video processor detects targets in midst of noise and discriminates radar echoes on the basis of their size. Target whose echo measurements are greater than those of the largest ship in range or tangential extent are usually land and are displayed only as normal radar video.
  • Page 106 Automatic acquisition areas and suppression lines Performance of auto-acquisition is enhanced by controlling the limit lines (suppression line) in the former series of FURUNO ARPAs. In this new series of ARPAs, the automatic acquisition rings are used instead of the limit lines.

  • Page 107: Factors Affecting Arpa Functions

    2.19 Factors Affecting ARPA Functions Sea returns If the radar anti-clutter control is adjusted properly, there is no serious effect because distant wave clutter, not eliminated by this control, is filtered out by more than one bang correlation and scan-to-scan matching of data. Rain and snow Clutter can be acquired and tracked as targets.
  • Page 108 Blind and shadow sectors Radar shadow or blind areas caused by obstructions aboard ship, for example, funnels and masts, in the path of the radar beam can result in reduction of radar beam intensity in that particular direction. This may eliminate the detection of some targets. The ARPA system will lose track of targets shortly after they are lost on the radar picture and if they remain in a blind zone.

  • Page 109: Chapter 3 Radar Observation

It is mainly dependent on the pulselength, antenna height, and signal processing such as main bang suppression and digital quantization.

  • Page 111: False Echoes

    False Echoes Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. They are, however, recognized if you understand the reason why they are displayed. Typical false echoes are shown below. Multiple echoes Multiple echoes occur when a transmitted pulse returns from a solid object like a large ship, bridge, or breakwater.

  • Page 112: Sart (Search And Rescue Transponder)

    Shadow sectors (see above right) Funnels, stacks, masts, or derricks in the path of the antenna block the radar beam. If the angle subtended at the scanner is more than a few degrees, a non-detecting sector may be produced. Within this sector targets can not be detected. SART (Search and Rescue Transponder) A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm.
  • Page 113 Summary to detect SART response 1. Use range scale of 6 or 12 nm as the spacing between the SART responses is about 0.6 nm (1125 m) to distinguish the SART. 2. Turn off the automatic clutter suppression. 3. Turn off the Interference Rejector. 4.

  • Page 114: Racon (Radar Beacon)

    Detuning the radar To increase the visibility of the SART in clutter conditions, the radar may be detuned to reduce the clutter without reducing the SART response. Radar with automatic frequency control may not permit manual detune of the equipment. Care should be taken in operating the radar in the detuned condition as other wanted navigational and anti-collision information may be removed.
