Problems solved by technology

[0004] The electromagnetic measurement systems known so far for collecting and analyzing astronomical signals are single receivers or sensors. Due to the constraints of the system, they can only be used to achieve rough judgments about general weather conditions, because when receiving astronomical signals, at most only Can determine the direction of the source position, but cannot determine the signal strength of the source position and the changes caused by different physical states of the atmosphere along the propagation path of the sky signal

Embodiment Construction

[0032] figure 1 Several measuring stations 2, 4 are arranged in a spatial region. In the illustrated example the measuring stations 2, 4 form an orthogonal grid network. However, the measuring stations 2, 4 do not necessarily have to be arranged in such an orthogonal grid. In the shown orthogonal grid network, the distance a between the measuring stations 2, 4 corresponding to the grid width of the grid network is less than 50 km, preferably between 10 km and 50 km, preferably about 30 km , which ensures that short-range astronomical signals can be collected by at least some of the adjacent measuring stations 2,4.

[0033] Each measuring station 2 , 4 has a transmission device 5 , which transmits the measurement data given by the measuring station 2 , 4 , derived from the sky signal or from other measured variables that may be recorded, to a central evaluation unit 6 .

[0034]A fixed-position direction-finding transmitter 8 , for example a timing transmitter DCF77 from Mai...

Abstract

The invention relates to a meteorological electromagnetic measuring system, comprising a plurality of measuring stations (2, 4) which are physically distributed in a given area. Each measuring station (2, 4) contains at least one spherics receiver (10a, 10b) to pick up a spherics signal and a transmission device (5) to transfer measuring data available in the measuring station (2, 4) and derived from the spherics signals to a central evaluation unit (6) assigned to said measuring stations (2, 4), wherein the average distance between each adjacent measuring station (2, 4) is less than 50 km for exhaustive detection of short-range spherics signals.

Description

technical field [0001] The invention relates to a meteorological electromagnetic measurement system, which collects and analyzes astronomical electrical signals. Background technique [0002] Sky signals are electromagnetic signals in the form of pulses of irregularly shaped rays that occur as dynamic processes in the atmosphere such as thunder or storm fronts or convective clouds. [0003] It is known from a large number of observations that various parameters of astronomical electrical signals, such as the number, amplitude, and frequency of oscillations, as well as the burst frequency, the frequency distribution on the frequency value and the shape of the signal are related to the weather process that caused the signal, especially the interaction with the atmosphere. Air species and movement are closely related. [0004] The electromagnetic measurement systems known so far for collecting and analyzing astronomical signals are single receivers or sensors. Due to the const...
