The task of measurements of the narrowband signals emitted by navigation and communication radios and broadband signals – radiation lightning arises in studies of the lower ionosphere by radio occultation of the Earth-ionosphere waveguide by low-frequency radio waves. Creating a universal receiver set for synchronous measurements of natural and artificial signals is of interest for increasing the information content of the data. The article discusses how to optimize the parameters of magnetic and electric field sensors to provide required bandwidth, dynamic range and matching with the input circuits of antenna amplifiers for noises. We present the algorithms for calculating the design parameters of the field sensors and a description of the pro-program-hardware complex for measurement of pulse and narrow band electromagnetic fields in the ELF and VLF ranges. The software part of the complex, implemented on a personal computer, allows estimating the absolute level, spectral composition, and polarization characteristics of the recorded pulse and narrowband fields in real time and storing the data around the clock.

Keywords: alternating magnetic field, atmospherics, inductive sensor
