摘要

本文讨论了不同测速系统中速度误差和振荡器频率稳定度的关系。由测速系统的传递函数对振荡器随机相位功率谱密度的抑制作用

得到了测速终端输入端Doppler信号的随机相位功率谱密度公式。文中还给出了速度采样方差

以及用最小二乘法平滑出速度的误差协方差矩阵与频率稳定度之间的关系。

Abstract

This paper discusses the relation of the range-rate error with oscillator frequency stability in different range-rate measuring systems. The formulas of the random phase power spectra density of the Doppler signal at the input of the range-rate measuring terminal are obtained from the random phase power spectra density of the frequency sources restrained by the transfer function of the range-rate measuring system. In this paper

the relations both of the variance of the range-rate samples and of the error covariance matrixes of the range-rate smoothed by least square method with the oscillator stability are given.
