Research on the Dynamic Test of Missile′s Altitude Channel

In order to test the whole performance of missile-borne radio altimeter,the theoretical and testing principle of the autopilot is analyzed, and the dynamic testing method is proposed, a programmable difference frequency signal generator has been developed to simulate the flying height of missile and make the auto-tester possessing the ability of dynamic test for altitude channel of missile, it′s also used in the emulation of whole missile trajectory.
