| 摘 要： | 针对被动雷达/红外（PRS/IRS）复合导引头的数据融合过程中两个不同采样频率的传感器测量数据时间不同步的问题,提出了基于最小二乘曲线拟合的时间对准方法,推导了最小二乘法的曲线拟合公式;分析了影响拟合精度的因素,提出了特定条件下同时满足实时性和拟合精度要求的最佳时间对准方案,并利用Matlab进行了仿真分析.仿真结果验证了该算法的有效性.

| Abstract: | Aimed at the asynchrony problem of time when two sensors with different sampling frequency measuring the data in the course of data fusion out of multimode seekers of the passive radar and infrared systems（PRS/IRS）,a time registration method based on the least squares curve fitting is proposed,the LS curve fitting formula derived,the factors of affecting the fitting precision analyzed,the optimum time registration scheme presented,which meets simultaneously the requirements for real-time and fitting precision in a particular situation in this paper.The simulation analysis performed by using Matlab,and the simulation results demonstrate that the proposed algorithm is of availability. |
