SYSTEM OF DETECTION, LOCALIZATION AND JAMMING OF A TARGET DRONE BY A DEFENSE DRONE AND BY A GROUND STATION (DRONEND)

The invention relates to a system for detection, localization and jamming of a target drone, using a ground station and a defense drone, as well as to methods for implementing the detection, localization and jamming functions within the system. According to the invention, the system comprises a ground station including an SDR platform USRP-X310 with spectrum detection function and function of identification of the incident direction of a signal coming from a drone, provided with two radiofrequency modules Twin-Rx with four phase-aligned reception channels, an SDR platform USRP B200mini for emitting a jamming signal, a host computer coupled via an Ethernet interface to the SDR platform USRP-X310 and via a USB cable to the SDR platform USRP B200mini, provided with spectrum detection algorithms and algorithms for identification of drone presence and direction, a jamming antenna provided with motor support for antenna orientation and a control module for the control of the motors of the motor support, also coupled to the host computer, with the role of adjusting the azimuth and elevation of the antenna emitting the jamming signal which can be amplified by means of a power amplifier and a defense drone with functions of estimation of incident direction for a target drone, as well as of transmitting a jamming signal thereto, for which purpose it is provided with an SDR platform USRP-E312, power supplied from an integrated storage battery having two transmission ports and two reception ports, and two receiver antennas. Invenţia se referă la un sistem de detecţie, localizare şi bruiere a unei drone ţintă folosind o staţie de la sol şi o dronă de apărare, precum şi la metode de implementare a funcţiilor de detecţie, localizare şi bruiere din cadrul sistemului. Sistemul conform invenţiei este alcătuit dintr-o staţie de la sol care cuprinde o platformă SDR USRP-X310 având funcţii de detecţie a spectrului şi de identificare a direcţiei de incidenţă a unui semnal provenit de la o dronă, echipată cu două module de radiofrecvenţă Twin-Rx având patru canale de recepţie aliniate în fază, o platformă SDR USRP B200 mini pentru emiterea unui semnal de bruiaj, un calculator gazdă, cuplat printr-o interfaţă Ethernet la platforma SDR USRP-X310 şi printr-un cablu USB la platforma SDR USRP B200 mini, prevăzut cu algoritmi de detecţie a spectrului şi de identificare a prezenţei dronelor şi a direcţiei acestora, o antenă de bruiaj prevăzută cu un suport motorizat de orientare a ante
