1. Contribution to Wideband SAR Space-Time Processing, and Radar Remote Sensing of Sea Ice
Sammanfattning : Synthetic Aperture Radar (SAR) has the capability to map the Earth with high resolution and is used in both civilian and military applications. The development of SAR systems is going towards higher resolution. Today there are Wide Band (WB) SAR instruments that have a resolution actually smaller than the operating wavelength. LÄS MER
2. Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements
Sammanfattning : Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. LÄS MER
3. On Spectral Estimation and Bistatic Clutter Suppression in Radar Systems
Sammanfattning : Target detection serve as one of the primary objectives in a radar system. From observations, contaminated by receiver thermal noise and interference, the processor needs to determine between target absence or target presence in the current measurements. LÄS MER
4. Waveform and Receiver Filter Selection for Wideband Radar Applications
Sammanfattning : This thesis concerns the design of transmitter-receiver chains for widebandradar systems. The transmitter side employs one, or several, highly flexiblesignal generators, which are able to generate signals with a large bandwidth. LÄS MER
5. Synthetic Aperture Radar Signal and Image Processing for Moving Target Indication and Side Lobe Suppression
Sammanfattning : The thesis summarizes a selection of my research within Synthetic Aperture Radar (SAR). Mainly the research is aimed at applying and developing signal processing methods to single channel and multi channel SAR for wideband systems. SAR systems can generate images looking very similar to optical pictures, i.e. LÄS MER
