General information

Cabinet of Ukraine Act # 1709 of December 19, 2001 ruled that the Facility for Remotely Sensing the Near-Earth Space  Environment at the Kharkiv V. N. Karazin National University Radiophysical Observatory is included in the State Register of Scientific Research Instruments that constitute a National Asset.


The instrumentation allows the researchers to investigate the various interacting processes operating in the ionosphere within an altitude range of ~60 19,000 km and the characteristics of radio-wave propagation within a frequency band of up to approximately 2 GHz, simultaneously with magnetometer measurements. The Radiophysical Observatory was completed  in 1980. Its completion resulted from efforts carried out by head of the Department of Space Radio Physics Prof. Misyura V. A. and numerous researchers (Dr. Podnos V. A., Assciate Professor Kapanin I. I., Dr. Kostrov L. S., Dr. Garmash K. P., Dorohov V. L. and many other professionals). Since 1980, the results of experiments and their interpretations, and results of theoretical or modeling studies have been published in more than 450 original research papers and have been represented at 78 scientific meetings (including 34 international meetings).


In 1995, the facility was involved in an international collaborative multi-site field campaign (Kharkiv V. N. Karazin National University, The Institute of Radio Astronomy (IRA) of the National Academy of Sciences of Ukraine, Radiophysical Research Institute (N. Novgorod, Russia), and the U.S.A.). The results of this study were published in leading international journals.

In 1997 1999 and 2001 2003, the facility was used in experiments supported  by the U.S.A. through  the Science and Technology Center in Ukraine  projects  471 (Prof. Tyrnov O. F.),  1772  (Prof. Chernogor L. F.), and 1773 (Prof. Tyrnov O. F.).

Space Research
The Department of Space Radio Physics places great emphasis on research, and supports several major groups, which have a worldwide reputation. It is unique in Ukraine in its studies of processes linking the surface of the Sun to interplanetary space, the Earth's magnetosphere and ionosphere. Back in the 1960s, the space physics group promoted and implemented clustered-instrument investigations of the ionosphere.

Department faculty, students and staff conduct research which concerns both measurements and theoretical interpretation, and is based on a range of experimental facilities available within easy reach of the Department at the Radiophysical Observatory.

The Radiophysical Observatory comprises an MF radar, a spaced antenna drift radar, a HF Doppler radar (at vertical and oblique incidence), satellite radio beacon receivers, a fluxgate magnetometer, a UHF receiver system, and an ionosonde. The instrumentation allows the processes acting in the ionosphere within an altitude range of ~60 to about 19,0000 km (navigation satellite orbit) and characteristics of radio-wave propagation on many frequencies within a frequency band of 30 kHz2 GHz to be investigated.

MF Radar Facility

The MF radar is used for investigating the lower ionosphere and mesosphere between 60- and 115-km altitude by means of the differential absorption experiment and the spaced antenna drift technique.



Elements of the MF radar antenna array



The radar operates in the 1.5 4.5 MHz frequency band, and consists of a 16-element linearly polarized transmitter antenna array of 300 x 300 m2 physical aperture, a circularly polarized receiving array of 2 crossed double rhombus antennas, and a polarization switch of 22 dB.


MF radar transmitter


The transmitter operates on a transmitter power level of 100 kW (peak power) and provides average power of 100 kW, pulse length of 20 micros up to continuous mode, and pulse repetition rate of 1 100 per second.




MF radar data acquisition and data processing system


The receiver has a dynamic range of 86 dB and an intermediate frequency bandwidth of 60 kHz. Both the antenna and the data acquisition system are reconfigurable from polarimeter to wind data acquisition.



Discrete perturbations in the ionospheric D region over Kharkiv region from the launch of the Space Shuttle at 15:13 LT on December 2, 1992

The facility permits the researchers to investigate a myriad of processes operating in the near-Earth space environment over time scales related to both natural and anthropogenic influences.


Accomplishment
A prominent accomplishment of the research that has been conducted with the MF radar is the development of a technique for sensing large (V/m) electric fields within the lower mesosphere remotely. This is the most exciting development, which gives very important original contribution to the global atmospheric electrical circuit. The results obtained with this MF radar fit neatly with other studies carried out as part of internationally coordinated research projects, mainly organized in the USA, under the banner of the ICSU body called SCOSTEP. The MF radar also allows the winds to be measured in the same part of the mesosphere simultaneously, thereby providing a means for studying the mechanisms for the generation of large mesospheric electric fields.

HF Doppler Radar Facility
The HF Doppler radar is used for investigating ionospheric plasma dynamics during disturbances, both natural and anthropogenic.

HF Doppler radar transmitting and receiving delta antennas

The principal radar part is a master oscillator of 1011 stability, and is capable of operating at a few frequencies in the 1.5 - 30 MHz frequency band at 0.01 Hz intervals. The techniques have been developed for acquiring measurements of undulating disturbances in F region parameters at vertical and oblique incidence in order to maximize altitude, spatial, and temporal coverage, and to detect variations over different time scales.

HF Doppler radar transmitter

The transmitter operates on a power level of 1 kW (peak power) and provides a 500-s pulse length at a pulse repetition rate of 100 200 per second.

HF Doppler radar data acquisition and data processing system

The receiver has a dynamic range of 80 dB, intermediate frequency bandwidths of 10 kHz and 20 kHz, a system bandwidth of 10 Hz, an instrument error of 0.01 Hz at a maximum Doppler frequency shift of 5 Hz.

 
Satellite Radio Beacon Receiving System
The Department of Space Radio Physics has acquired satellite radio beacon receivers for signals from satellites of "Cicada," GLONASS, and GPS systems. Satellite radio beacon observations may provide a powerful technology for studies of space weather effects upon total electron content and electron density irregularities with various spatial scale sizes.

Low-Erath orbiting Cicada satellite radio beacon receiving system antenna (in the foreground)

The analysis of dual-frequency Doppler shift measurements at one site permits the temporal and spatial features of total electron content to be determined and specified over a sufficiently large territory.

GLONASS and GPS data acquisition and data processing system


The collected satellite database is used to determine total electron content and the parameters of irregularity structure including traveling ionospheric disturbances in the mid-latitude F region during geomagnetically quiet and disturbed conditions.

Magnetometer
The magnetometer is installed at the Radiophysical Observatory. The data are autonomously recorded on a hard disk during about two months, and then the data have to be collected by a visiting researcher.



Data acquisition and data processing system

The magnetometer and data recording system acquire measurements in the south-north (H component) and west-east (D) directions at half-second intervals in the 0.001 -1 Hz frequency band within which the magnetometer delivers differential performance. The internal noise level shows the following frequency dependence: 0.5 pT at f = 1 Hz, 5 pT at f =0.1 Hz, and 50 pT at f = 0.01Hz.
