Karazin popup.description2 The research project is concerned with ionospheric dynamics and electrodynamics at middle latitudes during quiet and disturbed magnetic conditions. The research project aims at developing techniques for inferring information on space weather. It is needed for developing competitive ground-based and space-based communications and navigation systems. The research project applies methods of aeronomy, space dynamics and electrodynamics, random signal processing, and MF radar technique and data. A modern digital ionosonde have been designed. The following components have been designed and produced: the transmitter, the interface between the PC and the computer application to measurement and control (CAMAC) crate, the CAMAC controller, the Ch-31 frequency synthesizer controller, the R-399 receiver controller, the system synchronizer. Also, the analog-to-digital converters have been modified. The hardware, software, and techniques have been designed for determining electron density profiles and ionospheric virtual heights by using the phase technique. Also, the coherent Doppler integration technique and the angle of arrival measurement technique have been developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
