When I was in the army 1977 we used an ANPPS4 radar it had no screen just headphones it was good at picking up anything that moved. After a while a good operator could tell the diference between a tank and a tractor, truck or car people walking or a dear. This radar with a few tweeks would be as good as 70s coldwar tech. Cool...Thanx
I like it! Over here in l'il olde England quite a few years ago one of the mags featured a microwave link using a couple of mustard cans. As I recall, the circuit was a simple one transistor waveguide oscillator. Keep up the good work!
I designed such a radar as a hobby kit I sold at my old company for $69.95 - Called it the Speedy Speed Radar gun, still sold today. Used a 2 GHz transistor oscillator with hot carrier diode mixer on same epoxy glass PCB. Audio doppler signal was sent to a hand held display unit with 2 digit LED readout of speed. A whole lot simpler than this MIT mash-up, but then again, I only graduated from RIT! /s
Really nice project. On the range/time/Intensity plot there appears to be a second weaker signal, travelling 1m/s or so slower than yourself. Any idea what causes that?
There are certain types of radar that are called ground-penetrating radar which would certainly work better than a doppler radar, let alone one like this.
www.pasternack.com/2.5-ghz-radar-development-system-pem11000-kit-p.aspx for about $2400. I was looking to make my OWN board from scratch. Where are the schematics and part list?
Would an unused Directv dish be good for such a project? Perhaps use the can to transmit and the dish to receive for better sensitivity. I'm genuinely interested in trying this.
Sorry about the necropost, but an old dish like that would be _amazing_ for a project like this in terms of sensitivity and directivity (how tight the beam is)! However, it does (normally) add a bit of complexity, as most radars that use dishes use the same antenna for transmit and receive, which means you need to add logic to rapidly switch what the hardware is doing (if you accidentally feed the transmitter into the receiver, you will find yourself with a very expensive paperweight)
There COULD be one reason, which you can see explained even in the radio-stations and TV-stations. The sound comes from some source, goes through pre-amplification, into a mixer (with a gain control), then via the output to maybe the transmitter gear, which again can have several dampeners and amplifiers. Distortion can occur when the amplification of the entrance signal will result in a signal which exceed the power supply of the amplifier. This is a very known problem, and most sound systems for instance, has indicators for such oversteering-problems. So, you would often want to dampen an input signal to a level such that it does not oversteer the input amplifier. This is why you often have a GAIN-control on input side of amplifiers, such that an input signal does not oversteer. This is also why you would also have regulators on the output from the mixer, such that it does not oversteer the next stage in the sound... Whether or not this is the same here, I cannot say, however, it is a plausible explanation.
Hey IEEE, Will the receiver absorb all the energy from the signal or some can be reflected back ? I understand that the received signal is amplified. tha nks
Though it's looks simple...one should have good knowledge to build such a thing.. impressive Using knowledge for fun..most of us has bookish knowledge and in field we try to find something similar
Or you could just buy a Bushnell radar gun for all of $88 on Ebay (shipping included). I know the video is about building one yourself but if you don't have the know-how or the "couple hundred dollars in parts" to do it you can buy a brand new Bushnell brand radar gun rather cheap, which works up to 1500 feet (got one myself). Happy Holidays :)
Schematics and materials, the only thing we ever wanted
You can find them on MIT OCW website.

Thank you! You are great thanks
Cool project, nice construction, but you've gotta link us to the circuit diagrams at least!
hey you haven't uploaded in 3 years..

Ramsey sucks. Stopped makimg any good kits long ago.
Teach us how to design our own bro.
Thank you David. I'm going to try building this thing.
I hope I don't make a mess of it.
How did it go?
@@goatmeal5779 9 years too late
@@yayayayya4731I’m gonna be 11 years too late but I’m too interested in how it’s going

Congratulations, good project. Simple, compact.
Anyone know if there is any big changes to this set up if i'm using 5Ghz? Such as the size of the coffee can.
how did you record the data? can you explain please?
Good day sir, I really love this. Please could you provide a link I can get all these to build one please🙏?
Am eager to build one for my project
now that's interesting, though would it be capable of detecting police radar (even if it was in retrospect?)
The funny part is that this isn’t that far off ww2 radars
The Wire probe for the cans where can I get them
Very cool indeed.
Could this be used to map out caves & subterranean passages?

For schematics Google MIT Coffee Can Radar or Tin Can Radar Forum
Please provide links to details.
Just a quick question.
What surface did you mount/connect your RF components onto?
where can I find such a surface?
but there is no link in the description right now
what max object position range can be achieved from this set up ?
Do you have a parts list and a schematic you could share?
+Anthony Olive you can search for MIT synthetic radar project for more details. they have everything listed down.

for about $2400.

@@scrambledmandibleWould this be like programmed pulses with respective send and receive periods?
Does anyone know why you would want to attenuate a signal before amplifying it? Doesn't that seem counter productive?

I wonder how many milliwatts it emits. ...Watts?
how to have a ultrasonic capable of detecting object more than 20meters? :)
Can this be used as GPR?
What is the part list for this?

you have a strange way to cut your voice
That's look like a sensor more than a radar

There must be a better way to render a better visual, something more impressive?
#EXCELLENT!
it's a guide idea.
yes video does'nt really show/explain/clarify anything thanks
You can DEW it!
pure fun
Because it is a school project I am only in grade 4 I don't know how to make a radar
Nice, but I definitely will not be making this.
ok
Wow

It can not tell you direction of motion.
Mike Hawk can't measure distance.
