Method for identifying and one-dimensionally positioning multiple human body targets by using single-channel UWB-based radar life detection instrument

The invention discloses a method for identifying and one-dimensionally positioning multiple human body targets by using a single-channel ultra wideband-based (UWB) radar life detection instrument, which comprises the following steps of: A1, enhancing weak life signals of static human bodies, namely integrating the signals in the aspect of distance by a method for integrating 8 points at intervals of 4 points, scattering the signals, decomposing and reconfiguring to synthesize a target echo signal and a distance signal, and performing digital filtering and digital differentiation on the target echo signal to enhance weak useful signals; and A2, distinguishing a one-dimensional distance, namely analyzing spatial frequency according to the target echo signal subjected to digital filtering and digital differentiation and the distance signal to obtain the target one-dimensional distance.
