Operation 3. 2 Radar Map The radar display is a map-like representalion of the area in which the radar is operating. Typically, the ship's position is at the center of the display or sometime may be repositioned or offset up to 66% of the radius anywhere on the screen in the OFFSET MODE. The ship's dead ahead bearing is indicated by the heading line at the 0" bearing with every revolution of the sweep trace. Coastline contours are generally depicted in solid filled blue echo areas. Other surface vessels, and channel buoys, are displayed as smaller single echoes. The radar picture or map can be viewed in many sizes or scales from own ship. Greater detail of radar echoes nearby own ship is shown when using the short range scales. The best technique is to start with using a longer range scale and then switching to shorter ranges when nearby targets appear, or as the ship approaches the coastline, harbor, or other vessels in the area. Until the operator becomes familiar with interpreting the radar display, every opportunity should be taken to compare the radars display patterns with visual targets, such as other vessels, buoys, coastal structures etc. Harbor and coastal navigation should be practiced during daylight with clear weather conditions. 3. 2. 2 Effect of Ship's Movement Radar Displays can be drawn in two ways to show the ship's motion, The displays are called "Relative Motion" and `True Motion" Display.
