The multifunction display must be designated as the data master. Digital scanners offer: • • • Improved target definition. Full-color image. SuperHD option.
84 Sea clutter curve RayTech RNS V6.2 - User’s Guide 4. Click OK. Radar echoes from waves around your boat can clutter the center of the radar picture, making it difficult to detect real targets. Several factors can effect the level of clutter you see, such as the mounting height of the radar, weather and sea conditions. The sea clutter curve settings adjust the system’s sensitivity to sea clutter. The steepest setting is 1 and the shallowest is 8. The default setting is 1.
Chapter 11: Using the Radar (HD and SuperHD Digital) Note: When an open array antenna is fitted, the system stops the antenna in the forward facing position when Standby mode is selected. Range Radar range is limited by the height of your scanner and the height of the target, as illustrated below: Rmax a1 11.3 Radar range and image quality h Radar operates by transmitting radio pulses, then detecting the reflections as the pulses bounce back from objects within radar range.
86 RayTech RNS V6.2 - User’s Guide Image quality Side lobes Not all radar echoes are produced by valid targets. Spurious echoes may be caused by: Side lobe patterns are produced by small amounts of energy from the transmitted pulses that are radiated outside the narrow main beam.
Chapter 11: Using the Radar (HD and SuperHD Digital) 87 Indirect echoes Blind sectors There are several types of indirect echoes, or ‘ghost’ images. These sometimes have the appearance of true echoes, but in general they are intermittent and poorly defined. Obstructions such as funnels and masts near the radar antenna can obstruct the radar beam and cause radar shadows or ‘blind sectors’.
88 RayTech RNS V6.2 - User’s Guide Radar detects rain and snow. Returns from storm areas and rain squalls consist of countless small echoes which continually change in 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. This can occur when two or more radar-equipped vessels are operating within range of each other.

180 RayTech RNS V6.2 - User’s Guide Aerial imagery A high resolution, geo-referenced rasterized photograph taken from aerial or satellite sources. You can overlay your boat’s position on such an image, and get a visual estimation of your position with reference to actual, photography based landmarks. Navionics aerial photographs and Maptech Photo Region charts are examples of this type of chart. A.
181 Appendix B: Radar Introduction Scanner This appendix describes the basics of radar and things that can affect the radar picture. The radar scanner unit illuminates targets with microwave energy and then collects the reTurns from those targets. The scanner includes a sensitive low-noise front end receiver, and a variety of clutter attenuation controls to maintain target resolution. B.
182 RayTech RNS V6.2 - User’s Guide The following table shows typical maximum radar ranges for various radar antenna and target heights. Remember that although the radar horizon is greater than the optical horizon, the radar can only detect targets if a large enough target is above the radar horizon. Concentric range rings are included to help in the judging of distances on the radar picture. Their number and spacing are adjusted automatically if the range scale is changed.
183 The number of range rings shown in the table is the number to the selected range. Additional range rings are displayed to the edge of the radar picture, at the standard ring interval for the current range, and are visible when the center is offset. in the distance. In addition, some echoes may be indirect reTurns to the radar scanner, providing false echoes or multiple echoes. B.
184 RayTech RNS V6.2 - User’s Guide Side lobes False echo Main lobe Side lobe patterns are produced by small amounts of energy from the transmitted pulses that are radiated outside the narrow main beam. Side lobe Antenna Arc True echo Side echoes The effects of side lobes are most noticeable with targets at short ranges (normally below 3nm), 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.
185 Sea clutter D1642-1 D7053_1 True echo Multiple echoes Blind sectors or shadow effect Obstructions such as funnels and masts near the radar antenna may obstruct the radar beam and cause radar shadows or ‘blind sectors’. If the obstruction is relatively narrow, there will be a reduction of the beam intensity, though not necessarily a complete cut-off. However, for wider obstructions there may be a total loss of signal in the shadow area.
186 RayTech RNS V6.2 - User’s Guide Interference When two or more radar-equipped boats are operating within range of each other, mutual radar interference can occur. This usually appears as a spiral of small dots from the display center. This type of interference is most noticeable at long ranges.
187 Appendix C: Sonar C.1 Introduction C.3 Bottom indications The sonar provides a detailed underwater view that helps you to see bottom structure and texture, underwater obstructions such as wrecks and fish. Depth data is also provided and depth and temperature alarms can be set. The bottom usually produces a strong echo, enabling the sonar to see great detail. C.
188 RayTech RNS V6.2 - User’s Guide Notice that the lower layer of the image is shown as a lighter gray, indicating a weaker echo. This could mean that the upper layer is soft; some sound waves may get through this layer and be reflected by a more solid layer below. The same target will appear differently when the transducer frequency is changed. The lower the frequency, the broader the mark.
