Abstract:This study aims to enhance the spot position detection accuracy of four-quadrant detectors in laser guidance systems, thereby improving the tracking performance of laser weapon systems. To address the issue of interference from complex environmental noise, a fusion algorithm based on the reassigned Wigner–Ville distribution and time–frequency peak filtering is proposed. The algorithm effectively suppresses noise and enhances the time–frequency feature representation of laser spots through multi-component signal separation and reconstruction, combined with an intelligent analysis and iteration mechanism. The system was tested under functional vibration, random vibration, low-temperature, and high-temperature environments, with the critical metric of spot trajectory fluctuation rate reduced by 88.52%, 64.67%, 97.60%, and 86.39%,respectively, after filtering. The experimental results demonstrate that the proposed algorithm significantly enhances the stability and reliability of spot detection, providing key technical support for high-precision laser guidance.
