| Abstract: | The height measuring principle of FM-CW radio altimeter is described.The factors that have effect on the accuracy of height measuring in single frequency modulating altimeter are analyzed.The design scheme of a radio altimeter is put forward,which takes the microprocessor control system as the core,and is compatible with the two frequency modulation systems.Experiments show that,under the control of the microprocessor,the radio altimeter can dynamically choose appropriate frequency modulating mode at differ... |
