METHOD FOR CHECKING PHASE-TIME CHARACTERISTICS OF FERROMAGNETIC PHASE SHIFTERS Russian patent published in 2002 - IPC

FIELD: radar engineering; phase shifters for phased antenna arrays of radar. SUBSTANCE: measuring facility used for checking phase-shifter parameters has cathode-ray display tube that displays difference Δ between standard characteristic of ferromagnetic phase shifter and that under check as function of length τ of voltage pulse supplied to control winding used for evaluating degree of consistency between these characteristics, decision being taken in the course of adjusting phase shifter under check or its rejection. Proposed method may be optimized by displaying not only one functional dependence of difference Δ. but also set of different standards and sorting out phase shifters under check. EFFECT: facilitated adjustment due to better self-descriptiveness of parameters obtained. 2 cl, 2 dwg
