Radar Theory - Pulse, Bands, Attenuation and Discrimination

In this video I will compare the effect that X band and S band have on attenuation and bearing discrimination. I will also show how pulse length and band choice affect attenuation. Finally we will look at how pulse length determines range discrimination.

This is the clearest explanation on this topic that I've come across yet. Very helpful.

[@deckprep]

Thanks

Awesome explanation from Captain Steve Tarrant (if I am not mistaken). Teaching is a talent not everybody has. Many have knowledge but to convey information easily is another story.

[@deckprep]

Thanks for the nice comment!

[@johnmacintosh4432]

Awesome explanation. Thank You, Sir.

You're welcome

Very helpful! Can't say anything else. Greetings from Åland islands!

[@30myacht6]

Brilliant - absolutley superb!

[@deckprep]

I'm glad you liked it. It took a long time to figure out how to make those animations in PowerPoint!

[@marklacy5011]

Excellent refresher! Thanks

[@deckprep]

You're welcome!

[@xman7777]

Nice explanation...more nuggets of knowledge please 😀👍

[@deckprep]

Thanks. What kind of nuggets are you interested in?

[@NickNam3]

Beautiful Explanation, Thanks!

[@deckprep]

You're welcome!

[@boryspimentel3983]

REALLY HELPFUL 👍🏻👍🏻👍🏻

[@bhukyasama2957]

It is a clear cut explanation. thank you so much, Sir. Can you give explanation about radar earth curvature and about beam refraction

[@deckprep]

I don't have a deep understanding of refraction and I didn't teach much on that subject when I taught about radio wave propagation. I did find this online:
www.radartutorial.eu/07.waves/wa06.en.html
Do you have specific questions about refraction beyond the general theory?

Very nice. Thank you.

thanks so much for video.

Best video thank you.. perfect explanation

[@deckprep]

You're welcome

[@manaskumarpradhan9553]

thank for detailed explanation

[@deckprep]

You're welcome

1:34 ~ 1:36, is it better to understood the amplitude is diminishing instead of disappear ?

[@TheHarpanOnly]

This is what I looking for. My question, why X Band mostly used for navigation or surveillance radar instead of S Band while S Band will have farther detection range?

[@ParikshitBhujbal]

Fun and educating

[@deckprep]

Thanks

[@jairabelleventurillo9998]

Thank you very much sir!

[@ThePeyton301]

Take a look at the s band on icon of the seas. Damn thing is huge.

[@user-ht9oj5np1s]

Very helpful!! Thank you very much sir! 감사합니다!

[@deckprep]

You're welcome

[@connerfarr8072]

Couldn't we use software to discriminate between targets in line, knowing our pulse length we should know the pulse length of the returning pulse or eco. If we get a longer pulse than what we put out couldn't that represent more then one target or object present?

[@lyndalovon]

awesome!

[@deckprep]

Thanks!

This is very helpful. Thank you so much. Please more about navigation equipments. Subscribed by the way

[@abrahamcatalla6658]

Xband best for short range
Sband for long range

[@deckprep]

You are absolutely correct. Did I say something different in the video or did I just omit saying that?

[@byeongari8252]

whichis better to use/rely when in open sea and when near the shore?

[@deckprep]

In a ship setting, If you have both X and S band transceivers you will usually have one radar on X and the other on S. That is the best situation. I would use the X band to see greater detail on small ranges (6NM and less) and have the S band on longer ranges (6NM and more). If you are on a vessel with only an X band transceiver you will only use that.

[@byeongari8252]

@@deckprep thank you so much for the response, that’s really helpful. I’m a maritime student btw and I have a reporting tomorrow and that’s a good point to take into account 😁

[@deckprep]

I hope you have a safe and educational experience that builds your confidence and your skills.
