Description

technical field [0001] The invention relates to the technical field of amplitude and phase controller manufacturing, in particular to a program-controlled dual-channel amplitude and phase controller. Background technique [0002] The missile seeker needs to be tested on-site before leaving the factory to ensure the guidance accuracy. Among the current popular test methods, the flight direction and strike position are determined by two methods: the direction finding of the amplitude and the direction finding of the interferometer (comparing the phase). In the design and development process of the missile seeker, it is necessary for the signal source and other devices to provide signals of different amplitudes for testing the direction finding function of the missile seeker, and provide signals of different phases for the interferometer of the missile seeker. The direction finding (phase ratio) function is tested. [0003] Existing test methods usually use two general-purpose...
