I like on how he demonstrate... Very clear and understandable. This video will help my fellow seafarer to expand there learning. Its been highly appreciated🙏

Thank you.

Very nice video. Please cover all other equipments also like Speed log, AIS etc for SIRE 2.0 consideration.

[@nauticalacademy001]

Thank you. I will try to make video of other equipment in the future. Thanks

Do RADARs provide target "aspect" information?

[@nauticalacademy001]

Modern RADAR systems can provide target aspect information, but not all RADARs offer this feature directly. Aspect refers to the orientation of a target relative to your ship, essentially indicating whether the target is moving towards, away from, or across your position. RADAR systems equipped with Automatic Radar Plotting Aid (ARPA) or similar tracking capabilities can estimate the target's course and speed over ground, which can help you determine the target's aspect. However, this is often inferred from the tracking data, not a direct measurement from the RADAR. In simpler RADAR systems without ARPA or advanced tracking, aspect information isn't directly provided, and you would need to manually interpret it based on the target's movement over time relative to your own ship's position. In true vector mode, the vectors shown on the radar display represent the true course and speed of both your vessel and the targets relative to a fixed point (usually the Earth or a reference point on the ground). While this gives you the true motion of the target, aspect refers to the orientation of the target relative to your ship (i.e., whether the target is facing towards or away from your vessel). To determine the target's aspect, you would still need to analyze the target's course and compare it to your own vessel's position and movement. The radar’s true vector mode helps by providing accurate course and speed data, but it doesn’t directly display the target's aspect. True vector mode gives you more precise information about the target's movement, which can assist you in determining its aspect, but it doesn't automatically display the aspect itself. You would still need to analyze the target's course and compare it to your own vessel's position and movement.

@@nauticalacademy001 Thanks for your reply. Please, add more videos with scenarios on how to interpret and/or avoid misinterpretation of the PPI
