RTL-SDR Based Passive Aircraft Radar
Over on YouTube we’ve discovered a video from earlier in the year showing the RTL-SDR being used as a passive aircraft radar. This is different to ADS-B which is a type of active radar. A passive radar works by using a very strong radio signal from a readily available source such as a TV or FM radio transmitter and detecting the reflections from aircraft.
A RTL-SDR based passive radar system can be built by connecting two RTL-SDR dongles to a single clock source and by using two directional antennas.
We’ve also posted about RTL-SDR based passive radar being used to track aircraft here and here in the past. Another post about coherent multichannel RTL-SDR receivers can be found here.
Radar. I don’t think the word means what you think it means.
It appears to mean exactly what it says…. http://en.wikipedia.org/wiki/Passive_radar
Here’s a link with a description of doing doppler shift radar using the rtl-power program:

Where the software? One year of talking about it, but there is no description of how to do it
Yes unfortunately, we haven’t seen any public software or detailed tutorials about this type of thing yet.
i am pissed. why does nobody say how everyone can make something like that?!
Its nice to glue some dongle together and than? I found no Software, Howto or something else to do that.
Way to cool, I found a way to make GOLD with a Raspi but the riots in Ferguson ruined it all
I dont follow
