查询词典 noises

In order to decrease the measuring error of signal processing in laser Doppler velocimeter, frequency spectrum correction methods for lacer Doppler signal were proposed. Basic principles of energy centrobaric correction, ratio correction and phase difference correction were expounded. The three methods processing ideal sinusoidal signals was simulated with different signal frequencies, and so was the ratio method processing sinusoidal signals with different noises and signal to noise ratios.

在激光多普勒测速仪中，为了减小由信号处理算法带来的测量误差，提出运用频谱校正算法对多普勒信号的频谱进行校正，详细阐述了能量重心法、比值法和相位差法3种离散频谱校正算法的基本原理，运用这3种算法对理想正弦信号进行仿真，并运用比值法对信号施加不同频率和信噪比的噪音下的正弦信号和实测的多普勒信号进行仿真及实验研究。

In the low-low satellite to satellite gravity mission, the intersatellite range and range-rate data are the observable values, while the intersatellite acceleration can be derived from the range-rate through digital differential. Using acceleration data, people can avoid solving the variation equations of the satellite motion and simplify the observation equations. But on the other side, the digital differential will amplify the observation noises and finally affect the solved geopotential accuracy.

低低卫星跟踪卫星的观测量是两低轨卫星的星间距离或星间速度，星间加速度由星间速度通过数值微分导出，用星间加速度作为观测量可以避免解算卫星运动的变分方程，简化观测方程的建立，但数值微分会使观测噪声放大，从而影响重力位的解算精度。
