This thesis investigates the application of predistortion techniques in Frequency-Modulated Continuous-Wave (FMCW) radar systems, with a primary focus on enhancing range measurement accuracy and overall system performance. The study addresses the challenge of distortions in high-frequency radar designs, often resulting from non-ideal behavior of components, and examines the efficacy of predistortion in compensating for these imperfections. Initially, the thesis establishes a foundational understanding of FMCW radar operations, their application areas, and the intricacies of their components. It then explores the specific system model utilized for simulations, addressing the selected parameters and their consequences. The core of the research is presented through an analysis of simulation results, where the impacts of distortion and the benefits of predistortion on system performance are thoroughly examined. The study extends beyond theoretical models, incorporating real-world experiments to compare the performance of radar systems using both standard and predistorted signals. The research is driven by the goal of demonstrating how predistortion can bridge the gap between ideal model assumptions and the realities of component behaviors in radar systems. By integrating theoretical analysis, simulations, and empirical data, the thesis aims to offer a comprehensive insight into the vulnerabilities of FMCW radar systems and the potential improvements achievable through predistortion.
