Research Of Interferometer Direction Finding With Digital Multiple Baseline

The technology of digital multiple base line interferometer direction finding discussed in this paper is a project based on phase interferometer and high-speed digital signal processing technology. It can be used to aerospace electronics reconnaissance. The most of its research is made up of the phase and gain matched antenna with wide band, the phase and gain matched receiver with high sensitivity, the designing technology of high speed ADC, the method of digital phase discriminating, the method of de-ambiguity.This system can not only be used to high precision satellite electronics reconnaissance system, but also be used to air borne, ship-based and ground electronics intelligence reconnaissance system. It also can be used to the passive locating system of missile weapon system, and so on. It has quite expansive using prospect and potential benefits of military affairs .
