2. RADAR OPERATION 2.25.4 Terminating tracking of ARP targets When 10 targets have been acquired, no more targets may be acquired unless targets are cancelled. If you need to acquire additional targets, you must first cancel one or more individual targets, or all of the targets, using one of the procedures below.
Page 73: Setting Vector Attributes (Arp)
2.25.5 Setting vector attributes (ARP) What is a vector? A vector is a line extending from a tracked target which shows speed and course of the target. The vector tip shows an estimated position of the target after the selected vector time elapses. It can be useful to extend the vector length in order to evaluate the risk of collision with any target.
Page 74: Displaying Past Position Display (Arp)
2. RADAR OPERATION 2.25.6 Displaying past position display (ARP) This ARP can display time-spaced dots (maximum 10 dots) marking the past positions of any targets being tracked. You can evaluate a target’s actions by the spacing between dots. Below are examples of dot spacing and target movement. To turn the past position display on or off: 1.

Page 78: Interpreting The Radar Display
2. RADAR OPERATION 2.26 Interpreting the Radar Display 2.26.1 General Minimum and maximum ranges Minimum range The minimum range is defined by the shortest distance at which, using a scale of 1.5 or 0.75 nm, a target having an echoing area of 10 m from the point representing the antenna position.
Page 79 2. RADAR OPERATION Radar resolution There are two important factors in radar resolution (discrimination): bearing resolution and range resolution. Bearing resolution Bearing resolution is the ability of the radar to display the echoes received from two targets, which are at the same range and close together, as separate targets.
Page 80: False Echoes
2. RADAR OPERATION 2.26.2 False echoes Occasionally echo signals appear on the screen at positions where there is no target, or disappear even if there are targets. False target situations may be recognized, however, if you understand why they are displayed. Typical false echoes are shown below.
Page 81 Virtual image A relatively large target close to your ship may be shown at two positions on the screen. One of them is the true echo directly reflected by the target and the other is a false echo which is caused by the mirror effect of a large object on or close to your ship as shown in the figure below.
Page 82: Sart (Search And Rescue Transponder)
2. RADAR OPERATION 2.26.3 SART (Search and Rescue Transponder) A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band.
Page 83 2. RADAR OPERATION General procedure for detecting SART response 1. Use the range scale of 6 or 12 nm as the spacing between the SART responses is about 0.6 nm (1125 m) to distinguish the SART. 2. Turn off the automatic clutter suppression (if applicable). 3.
Page 84: Racon (Radar Beacon)
Some sets have automatic/manual anti-clutter rain control facilities in which case the operator should switch to manual. Note: This SART information is excerpted from IMO SN/Circ 197 Operation of Marine Radar for SART Detection. 2.26.4 Racon (Radar Beacon) A racon is a radar transponder which emits a characteristic signal when triggered by a ship’s radar (usually only the 3 centimeter band).
