摘要
阐述了调频连续波无线电高度表工作原理和仿真模型,在分析中考虑了垂直速度形成的多普勒效应.文中给出几种仿真计算的结果,分析计算结果可得知高度表的工作稳定性以及多普勒效应引起的动态误差.仿真计算程序可以应用于优化伺服系统参量或制作高度表的数学仿真器等多方面.
The priciples and simulation models of FM/CW radio altimeters are described, and the Doppler effects formed by vertical velocity are considered in the analysis. Different simulation results are presented, and by analysing the results we can know the stability of the altimeter and the dynamic errors due to Doppler effects.The computer simulation programs can be used to optimize the parameters of a servosystem and to make the digital simulators for altimeters.
