Background/Objectives: To evacuate trapped victims in complex environment with the help of UWB to detect the victim whether injured or not even before evacuation. Methods/Statistical Analysis: UWB system was used for sensing the breathing activity. In this process, the primary issue is the definition of design constraints about the signal processing waveform to transmit, correctly for the concerned algorithms for retrieving the breathing frequency and waveform precisely even in worst environment noise. Findings: The observation made from this study showed that more bitwise linear characteristic produced by the captured radar breathing signals than sinusoidal characteristics. Applications/ Improvements: The proposed system helps to find the status of the victim whether dead or alive; healthy or injured
