- The best use of radar in navigation is to use its accuracy at detecting the range of an object to give us a position circle. If we know the range of a charted object we can draw an arc at that distance from that object to give us a position line. As with any position line, we need to cross it with other position lines to get an accurate fix.

Mar 4, 2024 · A mandatory aid to navigation, the radar is used in identifying, tracking (with integrated ARPA) and positioning of vessels (including one’s own vessel) among other things in order to adhere to the COLREGs so as to safely navigate a ship from one point to another.
- CHOICE OF RANGE SCALE: Appropriate range scales should be used depending on the prevailing circumstances and conditions of the environment the ship is in.
- RANGE MEASUREMENT: Measurement of range to a target can be achieved either by the fixed range rings or the Variable Range Marker (VRM). The fixed range rings appear on the screen with a pre-determined interval depending upon the range scale in use and provide a rough estimate of the range to a target.
- BEARING MEASUREMENT: Electronic Bearing Lines is used to take the bearing of targets. The EBL extends from the own ship position to the circumference of the radar screen.
- GAIN: The gain control on the keyboard is used to adjust the sensitivity of the radar. It should be so adjusted that the background noise is just visible on the screen.

Radar ranges and bearings can be very useful for navigation. Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation. When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to ...

One of the primary benefits of radar is its ability to help you avoid collisions with other vessels and obstacles. By providing real-time information about the position, speed, and direction of nearby objects, radar allows you to make informed decisions about your course and speed to avoid potential hazards.
Apr 6, 2020 · While radar was once the only real option for blind navigation and collision avoidance, there is now a range of technology to help yachts wanting to see and be seen, but each of the options has its own strengths and limitations.
