Design and Implementation of In-situ Automatic Test for Radio Altimeter Based on an Altitude Simulator

To realize the automatic test of the radio altimeter system, a new automatic test method is designed. This method is based on a certain height simulator, takes the computer as the control core, and relies on a digital measuring instrument. It can not only test the overall performance of the object under test but also detect the specific fault of the object under test. The test process is controlled by software programming, and a personalized human-computer interaction interface is designed, which realizes the automation and intelligence of the test. The scheme has been validated by system tests and proved to be of great practical value.
