SIMULTANEOUS MEASUREMENTS OF THE POLARIZATION, ANGLES OF ARRIVAL, DOPPLER FREQUENCY, AND AMPLITUDE OF THE VHF RADIO SIGNAL FROM ETS-2

This paper gives a description of the transionospheric radiosonde (TIR) designed for simultaneous measurements of the main parameters of the ETS 2 radio signal at 136 MHz (polarization, angles of arrival, frequency Doppler shift, and amplitude, with a time resolution of 30 s; amplitude scintillations using spaced antennas with a resolution of 0.2 s). These data, referenced to exact time, are stored on magnetic tape and diskettes for the purpose of making a subsequent digital processing on a PDP-11 computer and personal computers. Data from the TIR radio interferometer can be useful when studying the dynamics of a geostationary satellite in orbit; when making a complex study of the transionospheric propagation of radio waves; and when studying the structure, dynamics, interaction, and transformation of ionospheric irregularities simultaneously in a wide range of scales (from 100 m to 1000 km). The objective of this paper is also to attract the researcher's attention to the data obtained by these authors, for possible cooperation on the level of problem formulation or joint secondary treatment and interpretation of data.
