Modeling and Simulation of Pulse Doppler Radar System Using Simulink

This paper presents the modeling and simulation methodology for a pulse Doppler radar system using Simulink. We begin with a comprehensive discussion of Simulink's fundamental concepts and capabilities, providing readers with essential background for understanding subsequent content. The implementation approach typically involves using Simulink's library browser to access signal processing blocks and RF components for system construction. Next, we explain the principles and operational mechanisms of pulse Doppler radar systems, covering key techniques such as pulse compression algorithms and Doppler effect processing. The pulse compression implementation often utilizes matched filters through Simulink's Digital Filter Design block, while Doppler processing employs FFT-based frequency analysis using Signal Processing Toolbox functions. Subsequently, we demonstrate how to model the complete pulse Doppler radar system in Simulink, incorporating transmitter, receiver, and signal processing chain components. The simulation experiments validate system performance and reliability through parameter sweeps and Monte Carlo simulations using Simulink's simulation manager. Finally, we summarize the paper's key findings and provide recommendations for further study along with reference materials. Through this paper, readers will gain comprehensive understanding of Simulink-based pulse Doppler radar system modeling and simulation techniques, providing valuable references and guidance for research and applications in related fields.
