Abstract: This thesis provides an overview of my research contributions in the field of Synthetic Aperture Radar (SAR). The primary focus of my research has been on the development of signal processing methods applied to both single-channel and multichannel wideband SAR systems. SAR systems have the capability to produce images comparable to optical photographs, with satellite-borne systems often achieving finer resolutions than their optical counterparts. Notably, SAR has been utilized for imaging celestial bodies such as the moon, Venus, and Saturn's satellites, obtaining high-resolution images. Additionally, SAR finds applications in detecting changes in ice sheets and monitoring deforestation. This thesis specifically examines SAR systems capable of high relative resolution imaging, utilizing data from the VHF system CARABAS-II and the UHF system LORA, both characterized by high relative bandwidth. Two key areas of focus in this thesis involve the detection and estimation of parameters associated with moving targets in SAR.. This structure allows for a comprehensive exploration of target detection and recognition models, their workflows, and their respective advantages and disadvantages. It also provides a foundation for researchers to understand the potential future directions and considerations for developing hybrid models in this field.
