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!

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.

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.

I've been following another series for building a guided rocket. I was looking for a video for radars as well and this looks promising, but the technology involved is beyond my understanding.
