Embodiment 1

[0024] Embodiment 1, the present embodiment discloses a data processing method of a non-standard format vertical detection ionogram, the ionogram data detected by the CADI type ionospheric vertical detector is taken as an example below to illustrate the data processing method:

[0025] Step S101, study the ionogram data format detected by the CADI-type ionospheric vertical detector, use computer programs to read out parameters such as detection time, frequency, height, and step size, and read out data such as the amplitude of reflected echoes and Doppler frequency shift .

[0026] Step S102, take the background noise value as the amplitude value of the invalid echo, and use the zero value as the Doppler frequency shift value of the invalid echo, and use the interpolation method to convert the frequency and height data in the non-standard format vertical detection ionogram data according to the SBF The standard format requires transformation; use the normalization method to con...

Abstract

The invention discloses a nonstandard format vertical sounding ionogram data processing method. A background noise value is used as the amplitude value of an invalid echo, a zero value is used as the Doppler frequency shift value of the invalid echo, and by means of the interpolation method, frequency and height data in nonstandard format vertical sounding ionogram data are transformed according to standard format requirements; by means of the normalization method, echo amplitude and echo Doppler frequency shift data in the nonstandard format vertical sounding ionogram data are transformed according to the standard format requirements, and the nonstandard format vertical sounding ionogram data are converted into standard ionogram data files. By means of the method, the different nonstandard format vertical sounding ionogram data are converted into current international standard data formats, and the purpose that the data are processed though international vertical sounding ionogram data processing software which is matured, universal and complete in function is achieved.

Description

technical field [0001] The invention relates to the technical field of ionospheric space environment detection, in particular to a data processing method for a non-standard format vertical detection ionogram. Background technique [0002] The ionosphere is a space region above 60 kilometers to about 1000 kilometers above the ground, where there are a large number of free electrons, which have an important impact on the propagation characteristics of radio signals. For example, the short-wave long-distance communication system is realized by the reflection of the ionosphere to the short-wave signal, and the electron density distribution of the ionosphere directly determines the available frequency band of the short-wave communication link. [0003] Carrying out ionospheric detection and data processing is the basis for ionospheric spatial environment characteristics research, modeling and forecasting, service and information assurance. Ionospheric vertical detection technolo...
