ADS-B, an acronym for Automatic Dependent Surveillance-Broadcast is a technology that allows tracking aircrafts using high speed radio transmissions. I have never had much interest in this technology until recently. While I was fiddling with this mode with Ian, we discovered a very simple way of demodulating this digital mode using the cheap DVB-T/FM (rtlsdr) [...]
A lot of users wanted to know who are the brains behind SDR# and instead of letting them speculating I decided to publish the list.
The main application without plugins is the work of two people:
Initial project setup DSP Core (What processes the radio data and renders audio etc.) The Waterfall [...]
SDR# has an original algorithm that compensates gain and phase imbalances between the IQ channels. Without this compensation strong signals are mirrored with respect to the center of the spectrum. All quadrature sampling receivers have their imaging problems. Solutions that were developed in this regard scale from manual adjustment of phase and gain parameters, to [...]
The code of the DSP is released under the MS-RSL license. This basically grants you the right to view the code for your own education, but you cannot redistribute it or redistribute modified copies (derived works.)
The rest of the application is under the MIT license.
