İnsansız hava araçları için düşük güçlü hafif tek girişli çok çıkışlı sentetik açıklık radarı sisteminin geliştirilmesi

Unmanned Aerial Vehicles (UAVs) are essential tools across various fields due to their flexibility, mobility, and cost-effectiveness. Integrating advanced radar systems into UAVs, however, poses challenges in power efficiency, payload weight, and real-time processing. This thesis presents a lightweight, low-power Single Input Multiple Output (SIMO) Frequency-Modulated Continuous Wave (FMCW) radar system tailored for UAVs. Initially, Stepped Frequency Continuous Wave (SFCW) radar was explored for its high resolution and subsurface sensing capabilities, but its limitations in speed and real-time processing led to the adoption of FMCW radar. The proposed system achieves real-time range and velocity measurements critical for UAV operations. Key features include multiple receiver channels for enhanced resolution and GPU-based computation for efficient SAR imaging. Extensive testing validated the radar's 50 cm range resolution and detection of objects up to 100 meters. The system's superior power efficiency and adaptability address existing UAV radar limitations, enabling applications such as obstacle detection, terrain mapping, and environmental monitoring. Future directions include algorithmic refinements, hardware miniaturization, and sensor integration.
