Respiration causes the chest to change in shape, which alters the target’s radar cross section, which causes periodical changes in the channel impulse response. A median filter, Viterbi algorithm and a particle filter are used to determine the range of the target, band-pass filtering and fourier transforming are used for respiration rate estimation. The results demonstrate that accurate localization and respiration rate monitoring is possible under controlled settings, but not in a realistic scenario.engProceedings paper10.1109/ipin66788.2025.11213365WOS:001828104600047TRAPPED VICTIMSRADAR
