| 摘 要： | 为了在不增加光学接收窗口数目的情况下提高光纤阵列激光告警器的定向精度,采用了一种新的告警定向算法,该算法将光纤延迟波形图从二维扩展到三维,并基于幅值强度矩阵进行角度解算,同时加入了虚警抑制。实际测试中对定向算法改进前后的告警角度分辨率进行对比,其绝对误差由5°改善到了2°。结果表明,该改进算法可以显著地提高告警器的定向精度。

| Abstract: | In order to improve the accuracy of directional detection with the same number of optical channels in the fiber-array laser receiving antenna,a new directional detection algorithm was been proposed,in which the two-dimension waveform data of time delay was expanded into three-dimension data,and the angles were calculated based on the matrix of echoed laser intensity,and the suppression of false alarm was also considered.Comparing the angular resolution with this algorithm before and after,its absolute accur... |
