“…In terms of research on multi-target detection methods, Zhang Yang proposed a variety of methods such as time-frequency analysis and improved constant false alarm rate (CFAR) to recognize multiple human targets at different distances [20,21]. Some researchers used the VMD algorithm to detect multiple human targets located at the same distance in an indoor environment and provide breathing frequency information [22,23]. Liu proposed a signal processing algorithm based on source separation and empirical mode decomposition to recognize and locate two subjects buried at different depths, which was able to extract the breathing features of the subjects but failed to capture the heartbeat frequency information [24].…”

“…In 2020, Shunqiao Sun and Athina P. Petropulu used matrix completion to compute the corresponding virtual uniform linear array (ULA) before estimating the target angle [4][5][6]. However, they verified the effectiveness of the ULA using only FFT and MUSIC.…”
