Abstract：This study aims to enhance the spot position detectionaccuracy offour-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 reasigned 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 inteligent 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.Theexperimentalresultsdemonstrate that theproposed algorithmsignificantly enhances the stabilityand reliability of spot detection，providing key technical support for high-precision laser guidance.
