Radar navigation - Wikipedia
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 establish arcs of position and lines of position on a chart.

雷达导航 - 百度百科
雷达导航（radar navigation）是无线电导航的一种。 利用雷达装置进行导航定位。 雷达从船上发射台向物标反射器发射脉冲电波，由接收装置接收电波的反射波，经放大检波后作为图像信号在阴极射线荧光屏上显示。 利用无线电波的直进性和等速性（电波传播速度等于3×10^8米/秒）可从荧光屏测得物标的方位和距离，从而测定船舰在海上的位置。 [1] 雷达导航（radar navigation）是无线电导航的一种。 利用雷达装置进行导航定位。
Radar determines distance to an object by measuring the time required for a radio signal (moving at the speed of light) to travel from a transmitting antenna to the object,
Maritime Safety Information - National Geospatial-Intelligence …
The Radar Navigation and Maneuvering Board Manual (Pub. 1310) contains, in a single volume, information on the fundamentals of shipboard radar, radar operation, collision avoidance, navigation by radar, and a description of vessel traffic systems in US waters.
Navigating the radar - Nautical Institute
Radar offers the navigator many useful functions for pilotage and coastal navigation: Parallel indexing and relative trails – for track monitoring and control; True vectors – to indicate the vessel’s ground track in steady state conditions; ARPA (also known as target tracking) – to acquire fixed objects to ground stabilise (echo ...
Navigation - Radar, Sonar, GPS | Britannica
Using radar, the navigator of a ship can see other vessels irrespective of light conditions. It is therefore safe for a craft to proceed—though slowly—even in thick fog, whereas without radar it would be necessary to heave to or anchor. Since the radar picture is imperfect, collision avoidance requires great skill in interpretation.
Marine radar - Wikipedia
Marine radars are X band or S band radars on ships, used to detect other ships and land hazards, to provide bearing and distance for collision avoidance and navigation at sea. [1]
Adaptive Radar Navigation | part of Position, Navigation, and …
In modern navigation systems, radar‐aiding methods can be divided into three broad categories: terrain aiding, velocity aiding, and relative position tracking methods. This chapter provides a high‐level overview of the purpose of stages in radar signal processing.
Radar - Imaging, Detection, Navigation | Britannica
Radar - Imaging, Detection, Navigation: Radar can distinguish one kind of target from another (such as a bird from an aircraft), and some systems are able to recognize specific classes of targets (for example, a commercial airliner as opposed to a military jet fighter).
Marine Radar and Its Uses in the Shipping Industry - Marine Insight
2024年3月4日 · What is Marine Radar? 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.
