第一组

A ship’s head up, or un-stabilised, radar display has the ship’s heading marker fixed at 000°, at the top of the screen. All targets, fixed or moving, then move relative to the ship’s position in the center of the screen and the heading marker. As the ship moves through the water, fixed target appear to track down the screen on a reciprocal heading at the speed the ship is moving and when the ship alters course targets appear to rotate in the opposite direction to that of the ship, so targets appear to move on the radar screen while the ship’s heading remains fixed. The coating on a radar display is

designed to allow a certain amount of afterglow（余辉）of targets, which in the ship’s head up mode causes smearing（拖尾）and may make the identification of smaller targets difficult. In addition, when targets, particularly large landmasses, are in close proximity interference occurs, which can further inhibit the detection of small targets.

89.When radar is set to ship’s head up display, all fixed targets displayed on the screen will appear

to ______.

A. track down the screen on a reciprocal heading at the speed the ship is moving

B. rotate in the same direction as the ship rotates

C. make the identification of smaller targets difficult

D. allow a certain amount of afterglow of targets

90.In the ship’s head up mode, if the ship rotates starboard-wise all fixed targets on the screen will

appear to ______.

A. rotate starboard-wise

B. rotate port-wise

C. remain stationary

D. move on a reciprocal heading at the speed the ship is moving

91.Afterglow of targets will ______.

A.have the ship’s heading marker fixed at 000°
