Item type:Publication, Access status: without files , Air object detection using pulsar FSROne possible algorithm of signal processing for airplane detection and parameters estimation using pulsar Forward Scattering Radar (FSR) is proposed. The algorithm for air target detection proposed in the article is intended for pulsar signal processing in a pulsar FSR system. The signal source is a pulsar, the receiver is a radio telescope, and the flying object is an airplane. The pulsar signal processing algorithm consists of a direct pulsar signal compensator and a detector of forward scattering signal obtained from aircraft. The proposed algorithm was simulated in the Matlab environment using a real pulsar signal.Publicationtype: Conference Paper52 - Some of the metrics are blocked by yourconsent settings
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 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Feasibility of Cosmic Object Detection Using a Solar FSR SystemThe article analyses the possibility of the forward scatter radar method for detecting large-sized cosmic objects when using emission of the Sun as probing signals. The method of the forward scatter radar is based on the phenomenon of a significant increase the bistatic target radar cross section when the probe signal is scattered forward, i.e. along direction of the principal beam of locator pattern.Publicationtype: Conference Paper141 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Feasibility of cosmic object detection using an X-ray FSR system(IEEE, 2019-06); ; ; ; The feasibility of an X-ray Forward Scatter Radar (FSR) system, which exploits X-ray pulsars as opportunity transmitters, is examined. We provide a power budget estimate for detection of large cosmic objects using such a FSR system and assume the use of the high-resolution X-ray telescopes mounted on a satellite as the receivers. The numerical results are obtained for three types of pulsars and small asteroids, whose diameters equal and overcome 50m.Publicationtype: Conference Paper314 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Multi-channel target shadow detection in GPS FSR(2019-03-29); ; ; ; The paper offers new application of a Multi-channel Forward Scatter Radar (MFSR), which uses GPS signals for detection of air targets on their GPS radio shadows. The multi-channel GPS MFSR detector consists of several channels, which process information from several satellites simultaneously. The phenomena of diffraction in the near area is used for shadow target detection. The target is considered to be detected, if it is detected at least in one of detector channels. Two experiments have been made to verify the proposed detection algorithm. The results obtained show that the proposed multi-channel detection algorithm can be successfully used for detection of low- flying air targets at very short distances or the near area of diffraction. Such targets are undetectable in GPS bistatic radar.Publicationtype: Journal ArticleScopus© Citations 4 429 309 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Observation of falling cosmic objects using GPS-based FSR(IEEE, 2018-08-27); ; ; ; In this paper, the possibility of GPS-based Forward Scatter Radar (GPS FSR), where satellites are exploited as sources of signals, to detect falling cosmic objects is examined. It is known that in FSR systems, the signal re-reflected by falling cosmic objects as masked by a much stronger direct signal. The goal of the article is to evaluate signal-to-noise ratio (SNR) of these signals at the detector input, after the correlator and the integrator. The results obtained show that the difference in SNR between direct and re-reflected signals is substantially dependent on the size of the falling object and the distance to it. The results obtained indicate what signal processing needs to be performed to separate the useful target signal from the direct signal.Publicationtype: Conference Paper137
