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 centre of the screen and the heading marker. As the ship moves through the water, fixed targets 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.
