DEFCON 19: Build your own Synthetic Aperture Radar

Speaker: Michael Scarito

Radar is used extensively by the military, police, weather, air travel, and maritime industries - why not you? Come learn how to build a radar imaging system on the cheap! This talk will explain the basics of how radar works as well as how to measure range and velocity of your chosen targets. You will learn how to use synthetic aperture techniques to generate a two- or even three-dimensional image. The hardware and software design will be totally opened up so you can go home and build your own system.

The talk will try to run through the basics pretty fast, so some knowledge of electronics or basic physics might help, but is not required! Regardless of your background, you will see the capabilities of a modern home-built radar system and hopefully get some ideas for your own uses.

Hi. That was very informative !!

[Christiaan008]

what part did you find the most informative?

[godimath]

first view and com <3

[Christiaan008]

still the first com!

TY for this vid! Nice work! Good talking, no shit, in name of all engineers: thank you

The radar equation was useful.

What *I* liked about it are your clear descriptions of enough of the basics to bootstrap a basic radar tutorial and showed pulse ranging & FM CW Then how to build the FM-CW on your table top = awesome. 2.4 GHz unlicensed band is def good enuf for radar. Mini-Circuits is a great source of RF HW, is that where you bought your LO?. Nice FM-CW demo. Any idea of Cantenna beamwidth? How's the crosstalk from XMIT can to RCV can? LO have enuf stability for SAR? Next step = digital downconvert to I&Q

Is it going to calm you down if I tell you that this technology is accessible to normal citizens. Well normal radio enthusiasts :)

[brandonhughes7]

wow seeing that image of the capital and knowing that it came from radar, is a little bit creepy. it just shows how easy it is for the government to watch what your doing 24/7

I love seeing people comment on these videos! Awesome!!!

Fantastic. Was a great refresher on communication and Radar theory. Once I've come by some money soon I may have a look into the tutorial.

Good thinking to build your proper radar but know how is works don`t said that you are Engineer but you are holy a constructor
