Abstract本文分析了FM/CW测距系统中的VCO频率—电压特性非线性因子对测距精度的影响,讨论了存在非线性因子时中频信号的频谱特性,提出了非线性因子导致中频调频特性的结论,给出了在这种情况下适用的距离估计方法。
Other AbstractIn this paper, effects of the nonlinear factor of the VCO of a FM CW ranging system are analyzed. Analysis on the spectrum of IF outputs shows that the nonlinear factor leads to FM effect of IF signal. A compensation algorithm is presented to obtain high accuracy of ranging result.
