AI Technical Summary
Existing technologies struggle to achieve accurate and efficient positioning of radioactive sources in complex and ever-changing real-world scenarios. Traditional methods suffer from high computational complexity, poor adaptability, and insufficient positioning accuracy.
A multi-detector radiation source localization method based on particle filtering algorithm is adopted. This method involves collaborative measurement by a mobile platform carrying multiple radiation detectors within the search area, calculation of particle weights using a radiation measurement model, and resampling when the signal-to-noise ratio threshold is met. The particle filtering process is optimized to improve localization accuracy and efficiency.
It achieves high-precision positioning of radioactive sources in complex environments, reduces computational complexity, improves system operating efficiency, and enhances adaptability to environmental conditions and positioning robustness.
