State of the Art and Problems of Defeat of Low, Slow and Small Unmanned Aerial Vehicles

Anotace: The article deals with one of the most intensively developing threats for civilian and military spheres – hostile use of Low, Slow and Small Unmanned Aerial Vehicles (LSS UAVs). The classification of the LSS UAVs is given. The existing threats of using LSS UAVs are divided into three categories. Special attention is paid to the third category of threats, the main feature of which is a high level of training of the operator. Main advantages and drawbacks of LSS UAVs are considered. It is determined that the best strategy is to employ a hierarchy of countermeasures including regulatory countermeasures (prevention, deterrence, denial), passive countermeasures (detection and interruption) and active countermeasures (destruction). State of the art and current problems of possible countermeasures are analysed. The most promising LSS UAVs’ counteraction technologies are described. Most attention is paid to specialized sensors and modern active counteraction means, such as programmable air burst munition and high-energy laser systems.
