| 摘 要： | 先从滤波器和信号的频域特性出发给出了滤波器在频域的采样率匹配原则。第二部分从滤波器预测误差最小的原则出发导出了一组求解最佳采样时间的方程，并给出部分计算结果。第三部分提出了速度平滑处理法，解决了提高采样率引起的速度估计误差增大的矛盾。随后给出了典型航路下，综合各影响因素的模拟跟踪结果，并与“×型”指挥仪的跟踪结果作了分析对比。最后提出了针对不同空中目标的最佳采样率的建议

| Abstract: | According to the frequency domain character of the filter and signal,the sampling rate matching principle of the filter in frequency domain is given in the first part of the paper.According to the principle of minimal prediction error of filters,a set of equations determining the optimal sampling interval time is deduced and some calculating results are given in the second part.In the third part,a method of rate smooth process is presented,which solves the problem of the enlargment of rate estimation error caused by the incresaing of sampling rate.Then the simulation results which synthesize all influence factors for typical tracks are given and compared with the tracking results of Some fire control equipment.finally,some suggestions of optimal sampling rate for various targets are presented. |
