1. 1. Preliminary Evaluation of the Clinical Value of an Ultra-Wideband Radar Sensor for Heart Assessment

   University essay from KTH/Skolan för teknik och hälsa (STH)

   Author : Kristoffer Lundbäck; Leonardo Dahn; [2016]
   Keywords : Ventricorder; Cardiac State Diagram CSD ; Ultra-Wideband Radar UWB ; Heart Monitoring; Electrocardiography ECG ; Ultrasound; Tissue Velocity Imaging TVI ; Ventricorder; Cardiac State Diagram CSD ; Ultra Wideband radar UWB ; Hjärtövervakning; Elektrokardiografi EKG ; Ultraljud; Tissue Velocity Imaging TVI ;

   Abstract : Heart dysfunction is a worldly widespread problem that currently is one of the leading causes of death. Studies indicate that many deaths related to cardiac dysfunction could have been prevented if discovered early. READ MORE

3. 2. Wall Compensation Algorithms for M-sequence UWB Radar

   University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Author : Mhd Jihad Abou Raas; [2016]
   Keywords : Ultra-wideband UWB ; Wall Compensation Algorithms;

   Abstract : A technique for wall compensation in the ultra-wideband (UWB) through-wall imaging radar is presented. The UWB system can be utilize in high precision measurements, but due to phase distortion and amplitude attenuation caused by the wall the precision is limited, the target is displaced, and the image is defocused.

4. 3. Evaluation of weighting functions for Sidelobe control in UWB SAR image processing

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Habiba Akhter; [2013]
   Keywords : Image processing; Synthetic aperture radar SAR ; Ultra Wideband UWB ; Apodization; Impulse Response IPR Function;

   Abstract : Ultra wideband (UWB) Synthetic Aperture Radar (SAR) holds huge possibilities for both terrestrial and celestial object sensing with excellent details which assists in science and technology. SAR systems associated with large antenna beamwidth, large signal bandwidth and low frequency operating in the VHF/UHF region is becoming gradually more popular because of their rising number of application in the areas of ground-penetrating radar (GPR) and foliage penetration radar (FOPEN).
