| Abstract: | This paper analyzes the working mechanism of aerodynamic missile-borne radio altimetre and puts forward a new design for the radio altimetre based on virtual instrument and I/Q modulator.By some instances of radio altimetre, dynamic test system is designed.Though the practice project,this new system actually can simulate the dynamic working progress of radio altimetre all-sidedly,and check out fault of altimetre as quickly as possible. |
