This paper simulates the operation of Frequency Modulated Continuous Wave Synthetic Aperture Radar (FMCW-SAR) with nonlinearity compensation to assess its impact on contrast and range resolution. The simulation generates an FMCW signal and models target movement at various velocities, illustrating how speed variations affect received signals and range profiles. Nonlinearity compensation mitigates distortions that could hinder target detection accuracy.
The analysis underscores the importance of signal processing in radar performance, with visualizations revealing insights into the relationship between target velocities and sensor energy. Additionally, the study explores object detection and tracking techniques to identify and follow moving humans in real-time video streams, particularly in border control scenarios. By utilizing a cascade classifier for face detection and hue channel tracking, the system effectively monitors individuals, enhancing safety and operational effectiveness in dynamic environments. Overall, this simulation provides valuable insights into FMCW-SAR performance and its applications in surveillance and target monitoring.
