TY - JOUR AU - Moon, Todd K AU - Bradshaw, Thomas PY - 2022/03/22 TI - Interior Target Tracking Using Digital Communications Signals for Bistatic Radar using GNU Radio JF - Proceedings of the GNU Radio Conference; Vol 6 No 1 (2021): Proceedings of the 11th GNU Radio Conference KW - N2 - 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 in- clude Doppler frequency extraction, using FFT or MUSIC-algorithm based processing, follow- ing 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 hard- ware. UR - https://pubs.gnuradio.org/index.php/grcon/article/view/111
