3. TARGET TRACKING (TT)
3-12
True vector
In the true motion mode, all fixed targets such as land, navigational marks and ships
at anchor remain stationary on the radar screen with vector length zero. But in the
presence of wind and/or current, the vectors appear on fixed targets representing the
reciprocal of set and drift affecting own ship unless set and drift values are properly
entered.
In the true vector mode, there are two types of stabilization: ground stabilization (True-
G) and sea stabilization (True-S). The stabilization mode is automatically selected ac-
cording to speed selection, as shown in the table below. Manual selection is available
with [Stabilization Mode] in the [SPD] page in the [Sensor Settings] menu.
Relative vector
Relative vectors on targets that are not moving over the ground such as land, naviga-
tional marks and ships at anchor will represent the reciprocal of own ship's ground
track. A target whose vector passes through own ship is on a collision course. (Dotted
lines in the figure are for explanation only.)
