TTW life sign detection by means of CW X-band radar, homeland security and rescue applications

The aim of this research works is to developed a very simple and efficient strategy to detect vital life signs in Through the wall (TTW) scenarios, by taking advantage of a simple detection scheme and by exploiting a properly designed measurement set-up working in X-band regime. In the proposed method of a light weight microwave system based on continuous wave X-Band rescue radar, implementation has been done through proper experimental set-up and a new model of detection schema has been performed. The information of life signal has been extracted from the backscattered electromagnetic field employing independent component analysis (ICA) algorithm which works as an effective blind source separation technique to separate vital sign through complex noise, interference and clutter removing. Comparing among different algorithm like ICA, ACMA, EFFICA, the most efficient one gives the expected outcome was ICA.
