Item type:Publication, Access status: with files , FSR systems for detection of air objects using cosmic radio emissions(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-02); ; ; ; The paper analyses the possibility of Forward Scatter Radar (FSR) systems to detect airplanes using cosmic emission from pulsars and planets (pulsar, Sun, Moon). A suboptimal multichannel algorithm for joint detection and evaluation of the parameters of the forward scattering signal created by an airplane (duration and velocity) is proposed, with preliminary compensation of the powerful direct signal emitted by cosmic sources (pulsar, Sun and Moon). The expressions for calculation of the Signal-to-Noise Ratio (SNR) at the input of the detector and the compensator are obtained. The detection characteristics are also obtained, and the requirements for the suppression coefficient of the compensator are evaluated. A methodology for calculating the maximum distance for detecting an aircraft using a described algorithm is proposed. The obtained results show that due to the Forward Scatter (FS) effect, there is the theoretical possibility to detect airplanes at close ranges by FSRs, which use very weak signals from cosmic sources.Publicationtype: Journal ArticleScopus© Citations 4 7 27 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , The study of possibility for airplane detection using a solar FSR systemThe article analyses the possibility for survemance airplanes by using solar radio emission in a forward scatter radar system. It's estimated as the magnitude of SNR at the input of the signal detector calculated depending on the size of airplanes, the way of the airplanes moving relative to the baseline (perpendicularly or parallel) for various values of the solar radio emission. The time of the contact of airplanes with the receiver beam influences on the duration of the signal received from airplanes. Changes in the angular width of the FS zone and in values of the aircraft FS RCS depending on the frequency values of the solar radio emission are also taken account in the calculation of SNR.Publicationtype: Conference Paper31 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Airplane Detection by FSR using cosmic radio emissions(2020-09-21); ; ; ; The paper analyses and compares the possibility for airplanes detection by a FSR system that exploits radio emission from such cosmic bodies as Moon, Sun and pulsars. This possibility is estimated as a magnitude of SNR at the input of the signal detector calculated depending on the frequency of reception, the size of airplanes, which are crossing the baseline of FSR at the approximately right angle and the distance from the receiver to airplanes.Publicationtype: Conference Paper139
