Chapter 7: Using the Radar 143 Chapter 7: Using the Radar 7.1 Introduction This chapter describes the basics of radar and the things that can affect your radar picture. It then shows you how to use your radar and its various functions including: • • • • • • • • 7.2 Changing orientation and motion mode. Getting the best radar picture. Measuring distances and bearings. Collision avoidance using Guard Zones, MARPA and AIS. Using waypoints to mark positions. Setting up the radar display. Radar alarms.
144 E Series Networked Display Reference Manual Maximum radar range Maximum radar range is essentially line of sight, so is limited by the height of the scanner and the height of the target as illustrated below: Rmax a1 h a2 Earth Radar Rmax = 2.
Chapter 7: Using the Radar 145 Side lobes Side lobe patterns are produced by small amounts of energy from the transmitted pulses that are radiated outside the narrow main beam. The effects of side lobes are most noticeable with targets at short ranges (normally below 3 nm), and in particular with larger objects. Side lobe echoes form either arcs on the radar screen similar to range rings, or a series of echoes forming a broken arc.
146 E Series Networked Display Reference Manual Multiple echoes Multiple echoes are not very common but can occur if there is a large target with a wide vertical surface at a comparatively short range. The transmitted signal will be reflected back and forth between the target and your own ship, resulting in multiple echoes, displayed beyond the range of the true target echo, but on the same bearing.
Chapter 7: Using the Radar 147 Rain or snow clutter D3967-4 The radar can see echoes from rain or snow. Returns from storm areas and rain squalls consist of countless small echoes that continuously change size, intensity and position. These returns sometimes appear as large hazy areas, depending on the intensity of the rainfall or snow in the storm cell. Interference D6601-2 When two or more radar equipped vessels are operating within range of each other mutual radar interference can occur.
148 Powering on/off the various scanner operating modes To control the power to the radar: SCANNER OFF RADAR SCANNER ON Select required operating mode D8397_1 TX Switch scanner ON or OFF The scanner icon in the data bar indicates the chosen status and is described as: Radar Radar status Mode icon Status description/ use Scanner on and transmitting. When SCANNER set to ON, select this mode to activate scan ner. This is the usual mode of operation.
Chapter 7: Using the Radar The radar picture You will need heading and position data for full functionality of your radar. A fast heading sensor is also needed for operation of MARPA and can maximize the performance of radar/chart overlay. With your radar scanner connected and the radar in transmit mode, the radar picture, provides a map like representation of the area in which the radar is operating e.g.
150 E Series Networked Display Reference Manual from the coastline. Although the coastline may be much nearer, it may not appear on the radar until the vessel is closer to shore. • Some targets, such as buoys and small boats, can be difficult to discern, because they do not present a consistent reflecting surface as they bob and toss about in the waves. Consequently, these echoes tend to fade and brighten and at times, to dis appear momentarily.
Chapter 7: Using the Radar 151 These orientation modes are used in conjunction with motion mode (see page 152) to control how your boat and radar relate to one another and how they are displayed on screen. Any changes that you make to the orientation of the radar are retained when you switch off. Head Up (H UP) This is the default mode for the radar application. e.
152 E Series Networked Display Reference Manual Course Up (C UP) e.g: N As your boat's heading changes: Radar picture fixed SHM rotates accordingly Current course upwards D8400_1 N If you select a new course, the picture will reset to display the new course upwards. The reference used for Course Up depends upon the information available at a given time. The system always prioritizes this information in the following order.: 1. 2. 3. 4. Bearing from origin to destination, i.e. intended course.
Chapter 7: Using the Radar 153 Relative motion (RM) with optional vessel offset When the motion mode is set to Relative, the position of your boat is fixed on the screen and all the targets move relative to the boat. 0 offset 1/ offset 3 2/ offset 3 D6842-2 You can specify whether the boat is fixed in the centre of the window (0 offset) or offset by 1/3 or 2/3 to increase the view ahead i.e. The default mode for the radar application is Relative with zero offset.
