Abstract

Detection of water targets is an open issue. The research addresses the challenge of water surface target detection by leveraging Frequency Modulated Continuous Wave (FMCW) radar systems, specifically focusing on overcoming limitations posed by atmospheric interference, vegetation cover, and environmental noise. A significant challenge is the presence of strong water spikes or ripples, particularly when dealing with small-sized targets. These spikes can cause targets to become nearly submerged in water clusters, complicating detection. Recognizing the effectiveness of FMCW radar in all-weather conditions and its ability to penetrate vegetation, the project aims to develop a MATLABbased algorithm for water surface detection. The algorithm undergoes validation through experiments, ensuring accurate range detection by processing real-world data. Initial steps involve target placement on a water surface, data extraction, and subsequent postprocessing steps, including Fast Fourier Transform (FFT), peak detection and range estimation. The developed algorithm demonstrates successful range estimation for water surface targets, showcasing practical application effectiveness. Insights from simulation data and Signal-to-Noise Ratio (SNR) experiments guide further refinement, emphasizing calibration, noise reduction, and optimal SNR management. The project's future trajectory envisions broader applications, such as enhanced maritime surveillance, improved range resolution for FMCW radar, and collaboration with industries to maximize its potential in diverse radar applications, ensuring continuous performance improvement.
