Radar Plotting Pdf In this video i show you how to complete a radar plot to find the cpa, tcpa, course, speed and aspect of a target vessel. Follow the steps provided to plot the relative motion line for the contact on a radar transfer plot sheet. check your answers and discuss the plot with the instructor when finished.
Radar Plotting Sheet Pdf From the centre of the radar plotting sheet, perpendicular to the line of approach draw a line which cuts the oa produced and measure this distance. this is the cpa. It explains how to perform a basic radar plot and calculate values. it also outlines how to adjust plots and calculations if a ship changes course, speed, or both. formulas and step by step instructions are provided for common radar plotting scenarios. The application of simple geometry on a plotting sheet, a paper record of the radar display (ppi) over an interval of time, will enable you to determine the collision risk and safe action. ####### 2 plot =o (original) ####### 3 plot = a (actual) ####### this gives the relative ####### course of the target ####### our boat is travelling up the ####### screen, so we need to take ####### away our speed from the target. ####### draw o – w: the distance we ####### travel in 12 minutes ####### o w = the way of our boat o a p w x.
Radar Plotting Sheet Since modern electronics are so agile, many mariners have not done an actual radar plot in those five year intervals. to brush up for the brush up, here is a quick refresher on radar plotting procedures. There are plenty of texts on how radar works and how to operate it. this guide has been stripped down to the most basic information necessary to do a plot and still cover it. Radar plotting is defined as the process by which a radar system tracks a target over time, utilizing specific parameters to select and monitor targets based on their movement and size, and estimating their direction, speed, and potential collision risks with other vessels. This video shows the basics of radar plotting using an example. the video teaches the viewer how to calculate the cpa, tcpa, course, speed, and aspect of the target from drawing a radar.
