RadioKrafter is a channel primarily focused on simple examples and tutorials of software defined radio (SDR), phased array beamforming, RADAR, and Python. The goal for most of these videos is to demonstrate concepts and provide a "hello world" starting point for these subjects. But it is definitely not the only way, or even the best way, to do these things! Leave a comment with other suggestions or any issues you see. Let's all learn this together!

this looks like a VHS from 1995
Can't wait for the next part
Awesome man! Really good stuff! 👌💪🏻
Nice
my 10000 watchlists adding new evidence againts me
Seriously Cool Stuff Man. Keep Learning, Keep Experimenting, LOVE IT !
i just finished a diy arduino sonar and felt smart and wanted to move into radar and now i feel dumb again trying to watch this lol. but what i do get is incredibly interesting.
Hi Jon, thanks for the video. Suppose, we transmit the same sinusoid over 2 Tx and receive the same on 2 Rx, can we get phase coherence (apart from the slight mismatch due to the slightly different properties of the connecting cable)? Have you ever checked this?
the detecteve is alrydy dead
can this be used with WiFi
Sure, add a wifi dongle to the raspberry pi
Is it possible to get rid off the noise?
Dude I could be your best friend
Lost me at $2800...
0:22 amen to sign on top 🙏🏻 God Bless you and your family 👍🙏🏻🙏🏻
Do you an example for 1Tx and 1Rx in python?
Yes, check out the pluto.py example here: github.com/analogdevicesinc/pyadi-iio/tree/master/examples
Wow! So nice, so professional and so clear the way he explains. Well done!!!
Can these kits still be purchased? I've looked on AD and Digikey but they are all out of stock.
Yes, sorry about that. We have trouble keeping them in stock. But more units should be available in a few months. The fastest way is to order on digikey, even if they say out of stock. Then they will ship as soon as they arrive at Analog Devices' warehouses.
What kind of an amplifier would you recommend for this setup? I'm just starting in the field and was thinking about building a drone tracking radar to learn, I'd like a bit more range to experiment. Thanks for the great videos!
HMC1082 is a popular PA for transmit at X band. Also HMC608LC4.
Can this be used for a DIY SAM site to set up a no fly zone around my house?
Thank God I came across this video! Big respect to the author!
What's the max range?
Really cool series!
This is all what I need to start with PlutoSDR
Are you providing any demo mid-release products? Its definitely non diy. Actual reciving and transmitting units seemed to be printed or somehow immersed on the surface of pcb, maybe multilayered pcb, and non standard pcb. The question is can one order such a set of pcbs on chinese pcb factories
Appreciate you
I love this stuff and the fiddling around with it 😀👍... Specially if it's all so explained in a good way. The sad thing is ( and i think many agree) that when i see the price of 2800 .... my hart skips a beat 😢.... I was hoping to see a video on how to build something similar but for absolutely nothing and by digging around in old electronics and find your parts.
Is it possible to get the GNURADIO Control block for the Phaser? Im trying to build a monopulse tracker with GNURADIO and the phaser
Yes, thank you for also posting this question to ez.analog.com, that's the right place for tech support. That makes it easier for us. But for everyone else, here's that post and answer: ez.analog.com/rf/f/q-a/584285/gnuradio-with-phaser/532432
Hello Jon, Thanks for these great Labs on PLUTO I finally had some time to go through installation-modification and testing My setup is running with a I7 on Ubuntu 22.04 with Python 3.10 and adi.version 0.0.16 Only one issue is dealing with pyplot that does not refresh the graph I patched with these lines plt.draw() #plt.show() plt.pause(0.05) plt.clf()
Thanks Patrick! Yes that's a better, more universal, way to update those plots. I use spyder IDE a lot, and that displays plots inline. But I like your changes and I should do those when I post the code. Thanks!
Big thanks for the great video. Could you please introduce some good reference for "stretch processing"? I did not actually understand what is stretch processing
"Radar Systems Analysis and Design Using MATLAB" has a good chapter on stretch processing.
@@jonkraft Thank you
What an OG!!!
Good explanations, but I don't find any interest in detecting things I can see directly with my own eyes ! View is the best technology ever developped !
can we connect that radar and zammer? auto track drone and shoot emp to drone to kill?
Turbine and propeller modulations are part of the radar target processing on Air Defense Radars. You can see Russian Bear bomber propellers at max Doppler range. The bomber itself needs to get closer before the Doppler tracker locks-on to it. But we also had pulse radar that saw the bombers if they were high enough (Beyond the Horizon) at twice the range of the Doppler radar.
The Pulse Doppler radars I worked on all had the closing velocities on the right of the clutter notch, and opening on the left.
Many thanks! So interresting. Theorical papers are easy to found. It is easy to build basics doppler low cost radar. Here, I discover the power of array and chirp in doppler.
Looking forward to the next video.
So cool. I wish i could afford the parts to build my own
This may sound like an insane question, but is there radar sensitive enough to both detect a mosquito at relatively near distance, but positively identify it due to counting the microdoppler of its wings beating at a certain hertz?
Got hooked. Will watch the whole series now.
Yeah. Let's low key help Ruzzians right now. Great job... -.-
Best series on practical radar fundamentals around. Can't wait for season 2! It has been super helpful to take the Phaser from a bit of complex hardware to useful experimentation.
Can Starlink hardware be converted/hacked into a radar? After all, it is already a 2d scanning phase array... maybe it can be hacked into working at different frequency than original Starlink system?
10 seconds and I subscribed.
Looking forward to your phased array series, it is probably one of the coolest applications of signal processing, RF electronics and EM theory I know of!
I love this wow. The algorithm works in my favor. Sub.
thanks for your time and effort
Only read the title. 1st thought, "DON'T TELL THE RUSSIANS!"
as someone who worked on radar for a short while, i am blown away with this project. i would be shocked if you're not snapped up by some defence contractor. or maybe that's how you got your knowledge? hehe
I just discovered this channel, instantly subscribed. Thank you for making these educational videos, I now have a bit of a backlog to work through.
This series is awesome!
