Radio-goniometric device for detecting frequency-hopping and direction, in VHF or UHF band

摘要

The radio goniometry detecting device (1) is composed of the collecting antenna arrangement (2) receiving the radio waves and a receiving unit (3) coupled with it. The arrangement consists of three dipole antennas (2a, 2b, 2c), with a switch (4) for the transmission lines (5, 6, 7) going to the receivers (8, 9, 10) and then to the spectral analyser (12) with three Fourier transforming units for the different wave types. There is, after this, a phase discriminator (13), a computer (14) and a display (11).
