一种基于相关干涉仪测向设备的校准源的研究与设计

orrelation Interferometer is one form of the Wave-Front direction finding technics. This system calculate the wave direction by getting the phase informations that carried by the signals, and also request for using multiple antenna array and multi-channel receiver. In the direction finding activities, the inconsistency of amplitude and phase that between the multi-channel receiver's channels always causes serious measurement errors. In order to solve this problem, this paper puts forward a kind of solution which use the calibration source to transmit, then the direction finding equipment receiving the calibration signal, and at last run the algorithm to complete the compensation for the balance of channels on the back-computer. This paper introduces the design of the calibration source which adopts the direct digital synthesizer for calibration source. Users can conveniently change the calibration signal. At last, proved the validity of the solution by commissioning and testing.
