ALGORITHMS OF DIGITAL PROCESSING OF AN EARTH NEAR-SURFACE ELECTRIC FIELD INTENSITY USING A KALMAN FILTER
Journal Title: Вестник КРАУНЦ. Физико-математические науки - Year 2018, Vol 3, Issue
Abstract
With the help of the Vaisala EFM550 electric field meter, long-term studies (2010-2017) of the course of the electric field strength in the area of the city of Nalchik were carried out. The article considers the use of digital processing to improve the quality of data obtained with a network of sensors operating in the hardware and software complex in the monitoring center of the geophysical situation over the southern region of the Russian Federation at the FSBI «High-Mountain Geophysical Institute». The possibilities of applying Kalman filtering to refine the data of instrumental measurements of the electric field strength of the atmosphere are investigated. A comparative analysis of the obtained data on the course of the electric field strength before and after filtration is given.
