NASA ARSET: Basics of Synthetic Aperture Radar (SAR), Session 1/4

Session Objectives:
- interpret the information in SAR images
- recognize distortions that need to be corrected in SAR images
- describe the basics of PolSAR and the information provided by different polarizations
- describe the basics of InSAR and the information in an interferogram

Vraiment inréressant. Merci pour tous ces renseignements

[@hemalathagonuguntla3714]

Thank you for clear explanation of basic concepts :)

[@loonyfrog]

Excellent content yet poor audio quality..

[@Mrrlamb1]

Wonderful content... Thank you!

[@dary6657]

Clear explanation, Thanks a lot!

[@NomanMustafascientist]

learning from someone who works at NASA .OMG! so phenomenal

[@moeshyassin]

Excellent presentation. Thank you ma'am.

[@Dobbs321]

Excellent review!

[@virajkadam3017]

Thanks a lot! This is amazing content

[@deepakjhirwal]

Very informative, thanks for educational video

[@ParisSamayam]

thank you so much for clear explanation about SAR

[@Hana-ww8nx]

Thank you so much can you share me that how can I get backscattering coefficients of sentinel 1

[@lingshen7234]

Thank you! Really helps me alot!!!

[@thenaturetalks595]

Thank you for great video: The Nature Talks

[@christopherbeebe9270]

@22:30 receiving a polarization through the use of a filter is mentioned. Did you mean there is software processing post-antenna to make sure only the energy from a given polarization is received? I'd like to know more if so.

[@karlleibdarius9818]

Nice explanation Erika

[@garriedaden4168]

Very helpful. Many thanks

[@bouabdellahlamani9751]

Thank you very match !

[@wildlifeireland9514]

Fantastic information

[@feiliu980]

there is a mistake about the incident angle. the figure give is right which is the angle between the incident light and the verticle direction, but what the video says seems to be wrong, which is the angle between the incident angle and earth surface

[@manamsetty2664]

Damn this stuff is available for free so cool

[@zynix27]

Some mighty amusing subtitles at 16:55...

[@Alternatives_Universum]

Danke

[@jsenthilmurugan5871]

Excellent

[@guswantnk]

Thanks

[@felixcrow]

Excellent presentation. Thank you.

[@Regressor14]

does Multi-look filtering related to FFT filtering?

[@jaweednazary8712]

Thanks for information, I think there is mistake on dialectic constant part. "The amount of moisture in the soil and vegetation will increase the strength of backscattered signal." It is the other way.

[@junxiang1110]

14:09, there is a mistake, she said " if the wavelength is much smaller than an object then there will be no or minimal interaction between the wavelength and the object".

[@manishmaurya6580]

so what is the actual concept?

[@eliseolopez2790]

Two types of remote observations passive and active passive measures energy emitted or reflected by the earths atmospheres system

Hello

[@SvSzYT]

thanks for the video. but the audio

[@johnkean6852]

_The basics_ : then comes a one hour long video 🤣

[@SouthernHerdsman]

Undergraduate level basics.

[@NickGhale]

Thanks nerd
