Abstract

Possibility of application of high-temperature superconducting (HTSC) filters in high-frequency (HF) radio direction finder is considered. Modeling of frequency responses of HTSC filters and direction finding accuracy is carried out using specific type oj filters. Requirements for the amplitude-frequency characteristics of these filters are imposed in order to reach high accuracy of direction finding.
