This is a really well done and quick presentation, on a topic that is extremely complex and sophisticated. Much appreciated for nerds like myself 🤓

[@bashkillszombies]

Did we watch the same video? This is cringe.

[@Usrthsbcufeh]

This was talking way too much about military and unnecessary details which have nothing to do with the actual technology

[@andile5945]

Thanks Holly well researched. Thanks again to everyone at QinetiQ.

[@geographerdiary8646]

Amazing job and perfect help for my today's presentation about the topic! Thank you!

[@MrMastera]

What a brilliant presentation, managing to explain such a complex device like the SAR in such a creative and thorough way and for such short time! Also, great left-handed drawing skills!

[@TheWizardGamez]

the d-riding is crazy

[@maxloveman3375]

Iam sorry to inform you, but she wrote right handed. Since you want to read what she is writing, the footage is propably mirrored.

[@MrMastera]

@@maxloveman3375 Thanks for pointing it out!

[@stopthenames]

Concisely explained, thank you.

[@zafarsultani]

Very good.your presentation style is appriciateable.

[@kainajones9393]

Enjoyed that style of teaching

[@jjsingh9838]

Very nicely explained, would like to know more

[@CorporalDirge]

Small antenna over large distances? What if we put one on a balloon and flew it over another country?

[@richardacevedo280]

Everybody wants a piece of the pie, except, the pie is ours. This technology has been well developed in the last nearly 20 years at least.

[@jordang1396]

Great video!

[@theodor320]

Is there any tips on textbooks which doesn't cost as much as my yearly tuition fee on SARs or other modern radar technologies?

[@farzansheikh1820]

I loved the idea of sketching everything after explaining, it really helped brainstorm the entire video at the end. *thumbs up*

[@conceptinmathematics6514]

Can you explain aperture synthesis in details? Everyone discusses the same what you presented here.

[@BlazeInjun]

Just watched a rocket launch from New Zealand putting a Sar satellite in orbit. Thank you.

[@ishankhan3537]

So simple explanation wow , hi I'm looking for information about radar based satellites that can detect objects in real time do you have that type of information??

[@clementdanladi6138]

This is good.

[@WillCarrKineticSculpture]

Such a great video, I love your hair :)

[@ylstorage7085]

Drawing the icons on a fancy board one stroke at a time DOES NOTHING to make the subject more clear but to waste everyone's time. You are not doing a complex calculation so that showing the intermediary steps is very beneficial.

[@sardarasif9065]

How much it cost small sar

[@spitfirefrench]

What was the point of the board?

[@Karum]

This seems to be the source of havana syndrome in combination with biometric information and tracking and a large fnirs brainwave database toolbox

[@putinimpotent2044]

Doesn’t really explain how SAR works. What about the different mode types, range vs angular resolution differences, etc?

[@SwissMarksman]

I think those are classified

[@johnnym.wright7644]

[@causewaykayak]

Mixed "comments" reception to this presentation. Looks like another weapon in the hands of law enforcement. Drones with automatic target recognition should sell well. Qinetiq develops weapons systems. This ad. parallels ones put out on behalf of GCHQ. Do you trust government enough to help them or is it just the prospect of being an Insider on a good salary ?

[@umurkaragoz]

Couldn't have thought a worse way to talk about something. Saying a sentence, and stopping for 10 seconds to draw something half-relevant to what is said, and repeating. Like wtf.

[@ottoomen5076]

There is a limited amount of information here. I apologize for being critical. best wishes.

[@AurovrataVenet]

Is this an explanation for kindergarten kids?

[@adrianobastardi]

Less is more, simple is best.

[@VrataVenet]

@@adrianobastardi might as well just play somee background music and keep mum then

[@authenticwarrior7877]

Lucid

untrue

[@MrPepto93]

IMHO this introduction is irrelevant. You cannot mix a material about such specific technique like SAR starting with what a radar is. For people who would need such introduction you can be sure that explaining SAR for them is pointless, even the term "aperture" would be infamiliar. My advice is to reformat this video, talking about SAR specific terminology/methodology with assumption that someone who is watching knows radar principles. Otherwise you end up talking about building a titanium reinforced wall construction for people who dont know what cement is.
