Rain Backscatter on 10 GHz

The site is still having troubles but Bing has got a cached result now:<p><a href="https:&#x2F;&#x2F;cc.bingj.com&#x2F;cache.aspx?q=10GHz+rain+backscatter&amp;d=703215632653&amp;mkt=en-US&amp;setlang=en-US&amp;w=tdmkjjO4G_xSw_XioepUt4IntZVdQa78" rel="nofollow">https:&#x2F;&#x2F;cc.bingj.com&#x2F;cache.aspx?q=10GHz+rain+backscatter&amp;d=7...</a>

Maybe not on the 3cm (10GHz) band but on 13cm (2.3&#x2F;2.4GHz) and even 70cm (430&#x2F;440mhz) there’s quite a lot of activity with aircraft scatter.<p>I’m still in awe that you can bounce a signal off a plane and get a useful and predictable bounce off it.<p><a href="http:&#x2F;&#x2F;www.airscout.eu&#x2F;screenshots.html" rel="nofollow">http:&#x2F;&#x2F;www.airscout.eu&#x2F;screenshots.html</a>

Hopefully the mass production of X-Ka band phased array antennas for Starlink and Kepler will bring the costs down for general purpose equipment. It would be really cool to be able to ’see’ the signal bouncing off of clouds and whatnot in the form of a raster image vs 2d fft.

This was cool, but I have no idea of what was achieved or what the significance of it was. Other than it was possible to receive a signal during heavy rain.

Is this like the ham radio site? <a href="http:&#x2F;&#x2F;www.wa1mba.org&#x2F;10grain.htm" rel="nofollow">http:&#x2F;&#x2F;www.wa1mba.org&#x2F;10grain.htm</a>

Does the scatter volume have to be kept small so that when the signal gets scattered at different positions, the path lengths and thereby the delay of the scattered signals do not diverge too much? If they did, the received signal would be &quot;blurred&quot; by receiving the signal overlayed by itself but with different delays. Is this the correct explanation here?

I guess the site got fried

Something is wrong with the database, it&#x27;s a PHP site...
