So on the basis of research on the altimetric measurement principle and test technology of the missile- borne radio altimeter, the dynamic testing method is proposed; y means of the functional ex panding for the existing automatictesting equipment, and developing the program mable PXI module to a difference frequency signal generator, the dynamic test for the radio altimeter and missile s altitude channel is real ized, which has value to the whole performance test of radio altimeters put into other application fields, and then provides references and beneficial attempts for the dynamic test of the other control systems of missiles. ey words: radio altimeter; Winged Missiles; dynamic test; difference frequency; PXI us 0 , , , ,
