Calibrating the Antennas,and we separately describe the relevant sets of devices. The necessary formulas are given to describe a calibrating capacitor, the gnome and radiating antennas, Helmholz rings, and the accuracy of calibration. Procedures are addressed of calibration at the field-site. A regular calibration is desira

Spectra of Continuous SR Background,us background signal. It is formed by a superposition of pulses arriving from ordinary lightning strokes distributed all over the globe, and those pulses arrive at an average rate of 50–100 events per second. We address the properties of natural SR background. It is impossible to mention every detai

Disturbances in SR,tric’ ionosphere modifications that occur simultaneously at the both polar regions. This is why the solar proton events (SPEs) are readily observed in the SR records. We address the published experimental data on SPEs and model these by using modification of the typical exponential conductivity prof

SR Line Splitting,y of ionospheric plasma arises when placed in the outer geomagnetic field. We account for this field in the framework of the hedgehog model: a constant radial magnetic field that abruptly changes its direction when crossing the equator. As a result, the ionosphere surface impedance becomes a tensor,

Signals in Adjoining Frequency Bands,There is the transverse (vertical) direction of radio wave propagation: between the ground surface and the lower edge of the ionosphere. In the present chapter we briefly describe the natural pulsed signals associated with the transverse resonance of the Earth–ionosphere cavity. This resonance occup
