TECHNOLOGICAL APPROACHES TO THE FORMATION OF DIGITAL IMAGES OF TERRAIN OBJECTS DURING REMOTE SENSING OF THE EARTH FROM PHOTO AND RADAR SYSTEMS

Abstract

The paper is devoted to the consideration of the current state and trends in the use of simulation modeling for mathematical modeling of terrain data obtained from the processing of digital images, both from photos and radar systems of Aerospace-based aircraft. The relevance of considering the state and trends in the development of technological approaches in modeling systems is due to the practical need to obtain data from photo and radar images of objects in the system's viewing area, taking into account the growing requirements for the efficiency and accuracy of determining (detecting) images of observation objects in real time in difficult conditions. The general structure of the construction of technologies used for simulation modeling of terrain objects is given the main prospects for practical application of these technologies in solving problems of classification and monitoring of terrain objects are determined. Estimates of the main technological approaches to images of objects in the application of the considered systems and assessment of the accuracy of determining terrain coordinates are given. Channels of information transmission in the process of receiving and processing data from photo and radar systems of remote sensing of the earth are considered. Also, as an example, a chain-node model of spatial data about objects that are obtained during remote sensing of the Earth and are represented as linear and point-based. To create a geographical basis for further modeling of various telecommunications and communication systems. This will allow for more accurate development of telecommunications and communication systems based on geographical data. Take into account the closing angles when forming a cellular connection.
