Well I got to thinkin . . . - Electronic Circuits Projects Diagrams Free

Crazy idea? You tell me.

How 'bout a radar tower mounted in my attic to see planes flying over my city? I was thinkin of using a microwave magnetron to generate the RADAR signal. Then I would imagine it would be pretty simple for a microprocessor to determine the reflection time.

Problem: Possible major interference from me that would most likely be rather illegal.

If it's not too illegal it would be a pretty cool project :lol:

That wod be realy hard to make.

And carful whith the magnetron so you dont fry evryhing around you.

As long as you dont interfear its probobly legal

Crazy and probably lethal :twisted:

It is a cool idea, BUT! Not sure were you live so it may be different for you. The wireless telegraph act is clear on what frequencies you may and may not transmit on, in order to have an effective radar system you would need to transmit in the microwave portion of the radio spectrum......

I n order to do this you MUST get a licence, an Amature radio licence would be easy to get, and then you could use the microwave alocation of the licence to experiment............. However the licence says you must transmit your call sign every 15 mins, or at the start and end of each transmitions which ever comes first................using any of the modes allocated to your licence.......

Getting boring now

Hope this has not put you off :lol:

Zach you do that in california and the FCC will be on your butt quicker then you can say jay.slovak

**Jay.slovak** · 14th October 2005, 10:15 PM

Good one Anthony :wink:

zachtheterrible · 15th October 2005, 06:15 AM

I'm not actually serious about doing this any time soon (if ever). It was kind of like my hood ornament idea :lol:

Anthony, I doubt the FCC would be on me, all they do anymore is sit on their butts and regulate the stuff on TV and radio. That's what I've heard about them in the US anyway

If you see an van whith an antena just quicky thurn it off.(Or blow up the van :twisted: )

Maybe I'll just turn it off :lol:

I don't see how I could transmit my call-sign. The magnetron would just be kickin' out an unmodulated sine wave.

Brilliant idea, excellent if you ask me.

But if you want to have kids, id leave it off until after you have kids.

Yes, thats another conern :lol: . Better leave this idea until I have much more experience in RF.

Someone Electro · 17th October 2005, 08:34 PM

You mean much much much more expirience.Since an radar is an prety complicated radio device.

zachtheterrible · 17th October 2005, 10:53 PM

Well it would be very easy to generate the radar signal. Just use a magnetron.

Actually it would be pretty simple overall. Just use the magnetron to radiate the RADAR signal, having the signal coming out of a satellite dish that spins. I would guess that there would be some method of using the satellite dish to also receive. The reflected signal would have to be amplified. Then that signal would be fed to a microcontroller that divides the speed of light by the time it took for the signal to get back (I think that's the way it works? :lol: ) then display a blip on the radar screen.

The prolem will be making the redio part becose your dealing whith GHz!
