| Abstract: | Aiming at the poor measurability of early radio altimeter an idea of testing in different layers has been brought forward in this paper.Through analyzing the test requirements of two common type of radio altimeters a feasible project of testing in different layers has been designed.The project is described by the test method,items,principle and result analysis.The software simulation has made it clear that the project can profounaly enhance test depth and the rate of troubleshooting.It overcomes the difficulty of testing altimeters efficiently and reaches the system design target.Compared with manual test it can advance work efficiency and shorten test period. |
