Multiscale Residual Attention Network for Distinguishing Stationary Humans and Common Animals Under Through-Wall Condition Using Ultra-Wideband Radar

Abstract: Distinguishing between humans and common animals through a wall is necessary for facilitating successful rescue of survivors and enhancing the confidence of rescuers in post-disaster search and rescue operations. However, few existing solutions are available with only dogs considered in this scenario. This poses an issue in ensuring the recognition accuracy involving different animal species. This work proposed a novel multiscale residual attention network for distinguishing between stationary humans and commo… Show more

“…UWB radar is widely used in ground-penetrating radar (GPR), through-wall imaging, post-earthquake rescue, and so on, due to its high range resolution and high penetration capability [1][2][3][4][5][6][7]. The frequently benefitted waveforms in UWB radar literature are short impulses [8][9][10][11], pseudo-random coded signals [12][13][14][15], frequencymodulated continuous wave (FMCW) signals [16][17][18][19][20], and stepped-frequency continuous wave (SFCW) signals [21][22][23][24]. UWB impulse radar has been increasingly adopted by researchers for human target detection due to its simple structure, low-cost, and low power consumption [25][26][27].…”

“…Bao et al [11] designed a cascaded spatialtemporal three-stage detector to accurately detect short-range targets and remove a few false alarms. In [12] and [13], two novel methods using support vector machine and convolution neural networks respectively are proposed to distinguish stationary human and common animals under through-wall condition. Common animals include some family pets such as dogs, cats, and rabbits.…”

“…In this case, UWB signal detection is based on analysing the identifiable Doppler shift patterns caused by the different gaits. In [ 13 ], deep learning is utilized in data postprocessing to help distinguish humans, three different animals, and empty room situations using through-the-wall UWB radar. The authors mentioned that the proposed technology can also be used in rescue applications, e.g., after earthquakes, to localize buried persons.…”

“…Not only applicable in residency environments, UWB radar is a feasible solution in rescue and other safety related operations, as presented in [ 13 , 22 ]. The dual use of analysis of the received signal can be utilized to observe and locate living persons inside ruins, an avalanche, etc.…”
