No Radar Topics?

There are no topics in Radar?

I'm kinda surprised!

Well - I might be starting some here soon. I've always wanted to build a weather radar. Cause I'm a weather buff.
I also used to work for a US University that did radar based research with flying things (birds, bats, bugs) -- but the radars we had were huge and a little unwieldy.

I always wanted to build something smaller (as did the scientists who did the research that I worked with.)

So, I've been collecting parts from units used for aviation to build something of my own... we shall see. :D

I like your idea! I wish I could work on something like that. At this point I have more projects than time left...

Check out this site for ideas.


Lots of other home-made projects there as well. Let me know on your progress, and feel free to post messages here or send info to me (UE@microw....101.com)

Good luck!

Hi guys, been thinking about building my own array for my car for a while now. It's sort of a big project which is why I'm so good at putting it off. I came up w a cool way to increase the directivity. After reading this string it seems I wasn't the only one to face this problem... just thought I'd put this out there, in case anyone want's to build a small array. Thanks to the mysterious Steve(^) it's up in the phased array antenna section of the encyclopedia here. Basically you use the orthogonality of a signal and it's octave. You can essentially get the directivity of an array twice the size of what you've got if you do it right. This eliminates the problem this guy was having in the article where he had to fake the directivity postprocesing, which can only work so well.

anyways, for anyone thinking of building their own small array, just thought I'd bring this to you're attention. It's useful I think for array's with 2-8 elements maybe, so more for hobbyists or small/cheap arrays than large scale military stuff.
