For quite a bit of the 1970s I worked in Marine Electronics, specializing in radar, gyro compasses, auto pilots, and telecommunications. I worked for Raytheon as a field engineer working on their commercial anti-collision radar. Some interesting radars I worked on were a Soviet S and X band radar where the S band wave guide and the x band wave guide were constructed like a coaxial cable - one inside the other. The slotted waveguide antenns were in the same scanner as a result. It was about 75' between the TR unit and the scanner and there were a lot of elbows in the wave guide along the route. Water was a serious problem and keeping them sealed was problematic. But my favorite radar was a hand-help chirp radar made by Whistler eponymously named Whistler Radar. It used headphones to listen to the beat frequency of the sent/received fm pulse. One curiousity is when aimed at a passing yacht one could here the vibrations of othe engine and stereo systems. These sounds vibrated the hull of the boat which modulated the radar echo (cw as you might expect) and speech was clearly understandable. Here and there in the internet are a few references to the Whistler Radar which was strapped on like an accordian and about the same size, head phones were donned, and targets were found to learn what the different sounds represented by visual objects, moving and stationary. I nearly got one recently on Ebay but it sold just hours before I saw it.

This content makes me wish my dad were still around these days, he loved tinkering with radio tech.

Fantastic work, Jon. The series is off to an auspicious start!

I am looking forward to seeing this series evolve. Great job!

very excited for this series - thank you for the time and effort put into these.

Excellent content. Appreciated all the work that went into preparing this. Looking forward to the series.

Awesome! I can hardly wait for the rest of the series 😁 Thanks 👍

I have always been fascinated by phase array technology. Very cool.

This looks quite interesting. I'm looking forward to your upcoming videos in the series

Fascinating series. Love the idea of starting simple and building to more complex experiments using a common base of hardware. It was the reference to Phaser, or phase-array antenna that got my attention on seeing the reference to this video. Watched a couple of prior videos, and am subscribed, ready to follow along.

Way back in the '60's in school we built a simple doppler radar. We used cans similar to what you are doing. Back then we used a klystron to generate the microwave signal, with what was called a hybrid junction to provide the detector and mixer. In the '80's I would have used a Gunn plexor to generate the microwave and do the mixing. I remember the term "radar mile," the time it took for a radar signal to leave the transmitter, reflect from an object a mile away, and return. My memory says about 63 microseconds, but I'm probably wrong, it's been many years. I'll have to follow your videos, thanks for sharing. Jim H.

glad you're back! looking forward to the rest of the series!

Wow... It was my childhood dream to learn and build RF electronics... Radar, radios etc... Thanks a lot for making this series

Fantastic content mate. Been waiting for something like this. Your facilitation style and content presentation is top notch. Keep it up!

This is gold. No unnecessary stuff. the SNR of these videos is just too damn high. love it. thank you so much. I wish your videos reaches to all the aspiring communication engineers

Fantastic. Subscribed. I am in the sports simulation space and have been working for a little while with vision based ball tracking systems. I know very little about radar but I always wanted to see if I could build something to track short range ball flight. Looking forward to this series!

The room and the video itself seems like a 90s TV worshop show... I love it!!!!

Nice work. I appreciate you applying your industry experience in explaining why you selected the components you did. Would not have thought to take an off the shelf SDR and modify the signal path! Can’t wait to see the rest of the series.

For a while I couldn't follow your videos. john, great job! Everything you provide in your videos is excellent material, especially for students of relevant specialties. Thanks very much!

Very interested, thank you for series! I've enjoyed CW only radars for many years, but ready to move on in experiments.

Great content Jon, Being a chip designer myself, I find it very informative to follow your videos I will be following this video series and will try to get the hardware as well

Jon, thanks so much for your time and effort. Looking forward to all the videos

This video was very good, it gave a presentation on the main aspects of radar systems. With practical examples from the most accessible to the most complex available for students and researchers. I just have to thank for your contribution.

Great presentation style. I'm looking forward to the rest of the series!

Excellent video and information. Looking forward to the next video parts.

Nice Jon - I work with a few drone radar companies. this came up in my feed. enjoying watching you building this from ground up.

This will be really exciting series.

Perfect! Since a few months back I'm having a phased array radar project in my head and on my bench - for detecting small drones! In addition I have acoustic profiling on my mind... 😉

Slick! I'm a retired ET who maintained the first phased array military RADAR SPS 32 on Enterprise back in the 70's. The electronics for each panel occupied (I think) 3 units full of control circuits, 4'X4'X7' tall, one with a single 8-bit register to run the phase shifting function. And to see such a FANTASTIC handheld device demonstrated so flawlessly is simply delightful. I'm going to make one to see how low those bloody helicopters are flying! Cheers!

Great teach and presentation skills! Can't wait to see the other videos!

Fantastic content... I hope it remains in the public realm without much difficulty.

I just found your channel and subscribed. I am a self taught "electrical engineer" specializing in vacuum tube high-end audio, particularly custom transformers, although in the course of my studies I came to really love math and electronics generally. I look forward to learning and working along with this project!

Analog Devices have some amazing engineers. It's always a pleasure to work with their products.

Happy new year! A very exciting project - a great start to 2024!

Outstanding video Jon. I write a lot of software and am fascinated by the combined engineering and software problem that is RADAR. I've been playing around with Vayyar's Walabot dev kit and its pretty robust and powerful. Still, I'd love to see more of this tech in the hobbyist/maker world, so these videos are an amazing resource.

your contribution is that you want to learn. Thank you. My dad was an Air Force JTAC/TACP and he tried to explain this to me but I didn't get it till I watched you learn and teach it.

This is cool as hell. Subscribed to see these builds. Thanks for breaking it down.

Been using the Doppler returns from VOR and ATSC tv pilot carrier signals for some experiments ... many A/C returns can be seen using waterfall type SDR receiver displays. Subbed to keep informed of your progress too. Thanks.

Great channel. Will be fun to go through your other videos. Subscribed. Cheers ...

am looking forward to seeing more of this video, thanks @Jon

I served on a SAM site for quite some time so PAR/CW systems are not unknown to me. We used PAR for longer, over the horizon tracking and CW for shorter and low-altitude tracking. I've been fascinated with radar systems ever since and always wanted to build a small, portable one at some point as I I'm an electronics engineer but my focus is on digital systems and uCs, never analog or RF. Maybe this is the chance to begin.

I'm hyped for this

I don't think I can afford the phaser. But this clip's got me interested, so I'm gonna keep tabs on this playlist. Thanks man for all the references, sure helps!

This is next level!

Oh this is gonna be right up my alley, thanks for this!

If 900 MHz is wavelength 30 ish cm then can it even detect small drones? Might work better, to locate the drone based on its own emissions.

Stumbled your channel by accident and found your delivery of contents very excellent. Such a complex field to grasp and understand you made it quite approachable and motivational. Remember the late Mr Jon Pease who delivered complex hardware into understandable real applications. Maybe a suggestion to explain math equations found in text books into real applications. Liked and subscribed

Amazing presentation! Thank you!

Fascinating subject! For a future video, I would be curious about a directional passive radar, but maybe I can figure it out from this series. Thanks!

Nice, my best friend works at analog devices too so maybe I should send him this, its a wonderful project!

ok this is cool as hell. thanks for this video was really informative and fun.

Amazing Dear Jon Kraft

Great idea. Thanks for sharing

This is very interesting. These are golden for hobbyists and amateurs to create something new. I can already think purpose like detecting a rodents or other harmful animals for farmers and have a systems to scare them off based to that.

Sounds fantastic.

Thank you. This is great . You are generous.

Thank you very much, this sounds like a fun project!

I work in digital design. Recently, due to project requirements, I had to learn more about embedded systems, specifically SDR. Actually, I feel a bit bored with this field. However, luckily I came across your channel. Keep it up, sir 🔥

Very interesting. Being a retired math guy with a love of radio astronomy and radio in general I will definitely follow your series. From the two prices I looked up, Pluto, & two low noise amplifiers, which together sums to about $360 & by guessing the mixers are not terribly pricey & guessing the phaser might add another $200 to the whole it's not terribly cost prohibitive. Especially if pursued over time. Regardless of whether I attempt to build a system which I'd love to do Pluto has really caught my attention & I think its on my next radio gear list. Look forward to the sequence & thanks for documenting & sharing.
