METHOD FOR IONOSPHERE SOUNDING AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2022 - IPC G01S1/32 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and is intended for environmental monitoring, radio communication, and navigation. Proposed for this purpose is an ionosphere sounding apparatus consisting of an operational amplifier, supplied to the non-inverse input whereof is a test signal from a harmonic signal generator, and connected to the inverse input whereof is an antenna, the directional pattern whereof is controlled by a unit connected to the first output of the processor. The non-inverse input of the operational amplifier is therein coupled with the input of the phase-shifting circuit, the output whereof is connected to the second input of the phase-sensitive detector and the first input whereof is connected to the output of the operational amplifier. The output of the phase-sensitive detector is connected to the first input of the measurement result recording unit, and the second input of said unit is connected to the second output of the processor.

EFFECT: increase in the accuracy and reliability of determining the parameters of radio wave propagation channels and simplification of the apparatus used therefor.
