METHOD OF ENSURING ELECTROMAGNETIC COMPATIBILITY OF SINGLE-POSITION IONOSONDE

摘要

FIELD: physics. ^ SUBSTANCE: method of ensuring electromagnetic compatibility of radioelectronic apparatus of a single-position ionosonde can be used in radio-wave vertical sounding equipment for diagnosing and monitoring ionospheric plasma layers. A linearly probing frequency-modulated signal with continuous variation of frequency in the working region of the ionosonde is generated. Centres of receiving and transmitting antennae are spaced out in the region of intense fall of the field of the transmitting antenna. The maximum operating power of the transmitter is determined in the following sequence: the minimum radiation power of the transmitter is measured, above which sections affected by noise from the transmitter begin to appear on the ionogram, and the maximum operating power of the transmitter which is not exceeded when using the ionosonde is calculated. ^ EFFECT: reduced loss of energy when generating and receiving signals which exclude switching noise and improved electromagnetic compatibility of the single-position ionosonde.
