1.17 FTC (Fast Time Constant)

If you can not effectively suppress rain clutter with the rain clutter control, use the FTC function. In adverse weather, clouds, rain or snow produce spray-like spurious echoes which impair target detection over a long distance. These echoes can be suppressed by turning on the FTC circuit. There are two FTC settings, [FTC1] and [FTC2]. [FTC2] provides increased rain clutter suppression.

Click the [FTC] icon at the bottom right corner on the screen to select an appropriate FTC setting.

FTC PRESET

The [FTC PRESET] function, when active, applies the FTC a little stronger than normal. The combination effect of the [FTC PRESET] and [FTC] functions is shown as below.

1.18 How to Measure the Range to a Target (VRM)

You can measure the range to a target by two methods: fixed range rings and the VRM (Variable Range Marker).

How to measure the range with the fixed range rings

Use the fixed range rings to get a rough estimate of the range to a target. The fixed range rings are the concentric solid circles about your ship. The number of rings changes with the selected range scale. The interval of the range ring is displayed at the upper-left corner of the screen. Count the number of rings between the center of the display and the target. Check the range ring interval and measure the distance of the echo from the nearest ring.

How to measure the range with a VRM

There are two VRMs, VRM1 and VRM2. The VRMs are dashed so that you can identify them from the fixed range rings. You can identify VRM1 from VRM2 by the lengths of their dashes. The dashes of the VRM1 are shorter than those of the VRM2.

5. To delete a VRM, put the cursor on the appropriate VRM indication then long press the left button (or long press the VRM key).

Note: If the corresponding EBL is displayed, the VRM is deleted and the value of VRM remains.

1.19 How to Measure the Bearing to a Target (EBL)

Use the Electronic Bearing Line (EBL) to take a bearing of a target. There are two EBLs, EBL1 and EBL2. Each EBL is a straight dashed line from the center of the screen to the edge. The dashes of the EBL1 are shorter than those of the EBL2.

How to measure the bearing with an EBL

1.22 Interference Rejecter

The radar interference can occur when your ship is near the radar of another ship that operates on the same frequency band with your radar. The interference shows on the screen as many bright dots. The dots can be random or in the shape of dotted lines that run from the center to the edge of the display. You can identify the interference from the normal echoes, because the interference does not appear in the same location on the next antenna rotation. When this feature is turned on, "IR 1", "IR 2" or "IR 3" appears at the bottom right corner on the screen.

Click the IR (Interference Rejection) icon to switch the setting among [IR OFF], [IR 1], [IR 2], [IR 3]. [IR 3] provides the highest degree of interference rejection.

To identify true target echoes from the sea clutter, echoes are averaged over succes-sive picture frames. If an echo is solid and stable, the echo is shown in its normal in-tensity. The brilliance of sea clutter is reduced to easily identify true targets from the sea clutter.

Note 1: Do not use the echo average function under heavy pitching and rolling to prevent loss of targets.

Note 2: This feature requires a heading signal and position data. When either signal becomes lost, echo average is deactivated.

To correctly use the echo average function, first reduce the sea clutter properly. Leave a little sea clutter on the screen so as not to erase weak targets. Then, do as follows:

The heading line indicates the ship's heading in all orientation modes. The heading line is a line from the own ship position to the outer edge of the radar display area and appears at zero degrees on the bearing scale in head-up mode. It changes its orientation depending on the ship orientation in north-up and true motion modes.

How to hide the heading line temporarily

To temporarily hide the heading line to look at targets existing dead ahead of own ship, press the HL OFF key on the control unit. Release the key to redisplay the heading line, etc.
