According to advance of radar technology and increase of air threat, 3D surveillance radars are preferred as shipboard equipments to shorten reaction time. In this paper, reaction time against air target was calculated by simulation in each case, 2D and 3D surveillance radar and it was suggested that a few parameters including purpose of warships, performance of shipboard equipments, threat of surrounding countries and budget to select the reasonable type of radar.

The surveillance radar for naval ships is an essential equipment of a battle system that executes the detection and tracking of targets, and the shooting support function; it calculates the three-dimensional track of the target range, azimuth, and altitude to carry out its duty. The surveillance radar consists of an antenna, a transceiver, a processing unit, and an air dryer section. The radar radiates the transmission signal on the antenna section, receives the reflected signal from the target, and amplifies the signals on the transceiver section. The signal received from the antenna is used to provide the operator with target information in various ways. This study identified the display problems when the information about the target is displayed through the radar. The causes of the problems were analyzed and improved. The tracking disappearance phenomenon caused by the altered-course of the ship was improved on the TWS tracking algorithm. The validity of the improved TWS tracking algorithm was confirmed by the normal condition of the target status on the B-scope.
