Plotting this new velocity information, due to the Doppler effect, shows whether a target is heading toward or away from you, and often reveals targets not normally seen in range-only information - this demonstrates the true power of full RADAR signal processing. FMCW RADAR experiments are enhanced to include Doppler processing. It is also possible to 'spatialise' the audio for the listener using stereo separation, which can convey a transmission's relative position on the spectrum. This will be demonstrated with a GNU Radio-based implementation. Modern SDRs can now sample the entire band, and as AM modulation is used, it's possible to use a counterintuitive, but simple, demodulator chain (first shown by Kevin Reid's wideband 'un-selective AM' receiver) to listen to the most powerful transmission. A good chunk of the VHF band is used for airline communications plane spotters enjoy listening to tower and cockpit communications. INMARSAT Aero will be revisited to show (in Google Earth) spatial information, such as waypoints and flight plans, that are transmitted from airline ground operations to airborne flights. The audience will be exposed to some novel GNU Radio tips and DSP tricks. The hacking continues on from last year! Three interesting applications will be demonstrated, and their underlying theory and design explained.

DEF CON 25 Wifi Village - Balint Seeber - Hacking Some More of the Wireless World Most of the radio related talks are in the 'WiFi Village' category.

Below is a selection of some interesting SDR and radio related talks that we have found. If you're interested in exploring the rest of the talks then you can find them on their YouTube page. Recently videos from the last Defcon 25 conference held in July 2017 have been uploaded to YouTube. Some of the talks relate to wireless and SDR concepts. NovemDefcon 25 SDR and Radio Related Talksĭefcon is a huge yearly conference based on the topics of information security and hacking.
