1. Detection and classification of buried objects using impulse radar measurements
Sammanfattning : .... LÄS MER
2. Signal Processing Techniques for Detection of Buried Landmines using Ground Penetrating Radar
Sammanfattning : The present thesis deals with the problem of detecting and classifying buried objects. The application in mind when addressing this problem is the detection of buried landmines. According to the International Committee of the Red Cross, about 100 million landmines are buried in 62 countries around the world. LÄS MER
3. Millimeter-Wave Impulse Radio
Sammanfattning : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. LÄS MER
4. Human Detection and Tracking with UWB radar
Sammanfattning : As robots and automated machineries are increasingly replacing the manual operations, protecting humans who are working in collaboration with these machines is becoming an increasingly important task. Technologies such as cameras, infra-red and seismic sensors as well as radar systems are used for presence detection and localization of human beings. LÄS MER
5. Temporal Characteristics of Boreal Forest Radar Measurements
Sammanfattning : Radar observations of forests are sensitive to seasonal changes, meteorological variables and variations in soil and tree water content. These phenomena cause temporal variations in radar measurements, limiting the accuracy of tree height and biomass estimates using radar data. LÄS MER
