Interior Target Tracking Using Digital Communications Signals for Bistatic Radar with Gnu Radio presented by Todd K. Moon, Thomas Bradshaw, Mirelle Despain, Jacob H. Gunther at GNU Radio Conference 2021 Wireless communication systems employed in buildings (such as WiFi) can be used for bistatic radar to track targets moving in the building. The transmit and receive hardware and software can be readily implemented using Gnu radio. The general processing steps at the receive include Doppler frequency extraction, using FFT or MUSIC-algorithm based processing, following by Viterbi or BCJR algorithm to smooth the frequency trajectory, followed by track extraction using an extended Kalman filter. The method has been implemented and tested using real hardware. https://events.gnuradio.org/event/8/contributions/123/ Source: https://www.youtube.com/watch?v=lHl4fMBp8DY Uploader: GNU Radio
