`Through-wall human being detection using UWB impulse radar
Ultra-wideband (UWB) impulse radar plays an important role in contactless vital sign (VS) detection. The VS can be extracted remotely by acquiring the oscillations in the human chest. Unfortunately, it is usually challenging to identify VS due to the low signal-to-noise ratio (SNR) only based on the traditional fast Fourier transform (FFT) especially in complicated conditions. To extract VS acc...
متن کاملUwb Radar in Hidden Human Detection
Hidden human detection and tracing have many civil and police security application. In this study, The UWB radars as the best system for human detection is discussed. For acquire the optimal result, proper antenna as a transmitter and receiver is presented. Gaussian signal as a suitable transmitter signal in UWB is presented. In the signal processing part two methods are debated and appropriate...
متن کاملThrough-wall detection of human being with compressed UWB radar data
The technology for through-wall human detection with ultra-wideband (UWB) radar was discussed. Due to the large amount of UWB radar data, compressive sensing theory was introduced and compressed UWB radar data can be collected. The singular value decomposition algorithm was used to acquire the singular values of compressed radar data. The compressed UWB radar data were collected at two statuses...
متن کاملSense through wall human detection using UWB radar
In this article, we discuss techniques for sense through wall human detection for different types of walls. We have focused on detection of stationary human target behind wall based on breathing movements. In detecting the breathing motion, a Doppler based method is used. Also a new approach based on short time Fourier transform is discussed and an already proposed clutter reduction technique b...
متن کاملDetection of trapped people by UWB radar
In this paper M-sequence ultra-wideband radar as a tool for the detection of people buried beneath rubble is described. Any strong enough motion of the victims modulates the signals detected by the radar. However, breathing is considered as the most beneficent type of motion, since it is present even when person is unconscious. Besides, the periodical nature of breathing makes it possible to di...
