Swabbing for explosives with organic semiconductor explosive sensors

Illegal migration of persons towards Europe produces new challenges in many domains in EU countries, but only in Croatia this phenomenon is linked with mine action. The Croatian borders are 2374 km long, and the one with Bosnia and Herzegovina, 1011,4 km long, is the most vulnerable. The Balkan illegal migration route from Bosnia and Herzegovina ends in Croatia where exist large hazardous suspected areas (HSA) which are marked with warning tables maintained by Croatian mine action center (CROMAC), which maintains on Internet the selectable scale maps of existing HSA. The MAC of Bosnia and Herzegovina has on the Internet the map of HSA at the constant scale 1:400,000. Illegal migrants cross the border outside the traffic routes and making the permanent space-time surveillance of the area impossible if done only by ground forces. The illegal migrants are exposed to high risk if enter the HSA. Croatian border police are exposed to very high risk while they have to repeat search while controlling the regions near the border. Although the border police have helicopters for the land border surveillance, only a dual sensor (visible color and longwave infrared – thermal) surveillance systems with remote piloted aircraft systems (RPAS) can be a sustainable solution for permanent control of this EU land border with HSA. The Mine Action experience of RPAS application for Non-Technical Survey (CROMAC) and Targeted Survey (NPA Bosnia) in „difficult“ terrains provides background for deployment the RPAS surveillance in considered new domain.
