Chapter 4 VRM AND EBL FUNCTION
4.3 EXAMPLE OF EBL FUNCTION
Example: EBL function.
Menu bar disappears after about 10 seconds.
How to change the EBL
Target bearing is displayed.
Flick on the screen, then the EBL line will move along
with the fingertip.
Turn the rotary knob to control the
movement of the EBL line.

ABOUT EBL/VRM FUNCTION
The target position and range information can be measured by EBL and VRM function.
Bearing measurement method:
(1) The RELATIVE BEARING which is measured from own ship heading line.
(2) The ABSOLUTE BEARING which is measured from the north line.
Certainly, ABSOLUTE BEARING is calculated by RELATIVE BEARING and GYRO BEARING.
So, to calculate the ABSOLUTE BEARING is necessary a signal from GYRO or GPS compasses.
In case of no external bearing signal, display only RELATIVE BEARING mode.
Target tracking function (TT) and display AIS symbol is necessary the GYRO or GPS compass signal.
When GYRO or GPS compass signal is received, normally azimuth is measured from the north (ABSOLUTE AZIMUTH).
This radar scanner has a microwave BEAM WIDTH is about 5.2 degrees (NKE-1066) or 4 degrees (NKE2044).
So every target echo has more than 5.2 degrees or 4 degrees width for bearing direction.
For above reason, in case of read out the target azimuth, you need set EBL line to the center of the target echo.
RANGE of target echo in any azimuth can be measured by the VRM function from own ship.
Target echo size is proportion to pulse length which transmitted from own ship.
In case of MEASURE SHORT RANGE ECHO using VRM, you need set r
ing to the echo’s nearest point from own ship.
At that point, you can get the correct RANGE for any pulse length.
