DEVELOPING A JAMMING SYSTEM FOR THE CIVIL DRONE

Abstract

 The development of modern technologies allows the unmanned aerial vehicles to successfully perform functions inaccessible in the past. They are gaining increasing popularity, are applied in different areas and solve a variety of tasks. These devices often use the wireless network technology IEEE 802.11. to communicate with the operator.

 A system for jamming the UAVs, working by the IEEE 802.11 standard. The system includes hardware based on the NI USRP-2953R equipment, and software using the LabVIEW software environment. The UAV jamming is carried out from a personal computer. For jamming, when an unmanned aerial vehicle enters the zone of visibility, the operator should direct the antenna to hit, after which carry out the launch of the developed program. The user can manage the input data and visualize the results of the experiment. 

 The derivation of the BPSK, QPSK, 16-QAM and 64-QAM manipulation algorithms in the LabVIEW software environment is developed and presented.

 The results of the system testing are given when the objects of jamming were the Wi-Fi network router and the Parrot AR Drone 2.0 quadrocopter.

The design of the antenna “Yaggi -Uda” is described.  The antenna is modelled by using one of the most powerful modern programs of electrodynamic simulation, the FEKO, which represents a new approach to the design of three-dimensional microwave devices. The proposed method allows varying the input data, calculating and designing the antennae at a given frequency. The calculation results are displayed in the form of graphs. The patterns of the mentioned antenna in the E and H planes in the polar system are presented. The value of the main lobe of the pattern at half power are calculated. The dependences of the standing wave ratio (SWR) and the gain coefficient in the operating frequency range 2,41…2,48 GHz are presented.
