In the face of today’s geopolitical conflicts, unmanned aerial systems (UAS) dominate modern warfare, with both Ukraine and Russia invoking drones in their ongoing battle, and more militaries developing UAS programs worldwide. While Counter Unmanned Aerial Systems (CUAS) are designed to respond — helping to detect, disrupt, disarm and defeat airborne vehicles — civil and military operations across the globe are hard-pressed to keep up with the demand
It’s become increasingly clear that the proliferation of drones across positive applications and use cases is driving modern civilization toward a new drone-driven society. However, enabling the emerging associated drone-powered economy will require a new generation of counter-drone or counter-unmanned aircraft systems (CUAS) to support the growth of safe and secure drone adoption. Innovative technology and solutions are imperative to defend against parallel rogue drone threats and highly advanced technologies are necessary to overcome rogue drone threats. This is because they can safely operate in even the most sensitive and crowded environments and airspace, as well as in a controlled manner that ultimately supports continuity
More airports are starting to adopt and test the use of radio frequency (RF) mitigation techniques to counter the operation of unmanned aircraft systems (UAS) in violation of civilian airspace rules. While civilian aviation regulatory agencies are welcoming the integration of more commercially operated UAS into civilian airspace, airports are responding to the growing number of incidents in recent years with counter measures to ensure drones do not interfere with regular operations. In the U.S., the Federal Aviation Authority (FAA) now receives more than 100 reports per month from pilots that have observed UAS operating near airports or within a restricted area of civilian airspace. The problem is a unique one for the FAA and other civilian aviation regulatory agencies who want to unleash as much commercial UAS innovation as possible within civilian airspace, but simultaneously recognize rogue operators are a problem. The FAA's method for addressing the operation of drones near
As commercial drone technology continues to expand, small unmanned aircraft systems (sUAS) are making it increasingly difficult to secure battlefields and military installations. In response to these challenges, Trust Automation has developed an innovative counter sUAS system to disrupt and defeat hostile unmanned aircraft system (UAS) threats at the field level. Called the Ghoul-Tool Attachable Transmitter (GAT), this compact, weapons-mountable system is the easiest way to field a jammer for UAS, providing command and control (C2), radio frequency (RF) and global positioning system (GPS) denial capabilities. Measuring just 6 inches long and 3.2 inches across and weighing less than a pound, it also supports mounting configurations on the side and bottom of small arms via a standard NATO accessory rail. A handheld grip also allows for standalone use
Operating beyond the visible light spectrum, forward-looking infrared (FLIR) cameras use a thermographic imager (camera) that senses infrared radiation, or heat signatures. Advanced FLIR thermal imaging systems capture and display infrared wavelengths that are radiating energy. Infrared thermography consists of three specific wavelengths, including short-wave infrared (SWIR), midwave infrared (MWIR), and long wavelength infrared (LWIR). MWIR imaging cameras have long been the preferred solution for clear thermal imaging at distances greater than one kilometer (km) for defense, unmanned aircraft systems (UAS), counter-UAS, security, and other long-range surveillance applications. To meet these imaging requirements, advanced MWIR camera systems are commonly integrated with infrared telescopes that feature a continuous zoom (CZ) lens assembly. Developing custom cameras and CZ lenses can be costly in terms of time and resources, and it can become complicated

Producing a set of well-calibrated imagery, both conventional LWIR thermal (watts/cm2-sr) and its corresponding polarimetric imagery (percent radiance polarized), helps evaluate the ability to distinguish between small UAVs and birds of similar size and dimensions. Army Research Laboratory, Adelphi, Maryland Currently, agencies within the Department of Defense (DOD) and the private sector are trying to develop techniques capable of detecting the presence of small unmanned aerial vehicles (UAVs) at ranges on the order of 1-5 km. Often complicating this effort is the presence of small birds of similar dimensions that are frequently mistaken to be small UAVs when imaged using various methodologies, such as visible, short-wave infrared (SWIR) and thermal imaging. Initially, research was limited to long-wave infrared (LWIR) thermal imaging that, in theory, should be effective for both day- and night-time operation. The goal was to record a preliminary set of calibrated radiometric and
Today's drone threat calls for small and lightweight radars with excellent detection range and coverage. That's already tricky, as most radars do either one or the other. In the planning of IRIS, a new drone radar system, Robin Radar Systems pledged not to make that compromise. That is a steep task from a technical perspective, without throwing in a small and lightweight form factor and full coverage into the mix. IRIS was designed to be easily lifted, transported and deployed and redeployed as needed, which is pretty unusual for most radar systems. Starting from scratch, that gave Robin Radar's technical team only two and a half years to transform an almost blank sheet of paper, except for a few high-level specifications, into a working product. The big question is, how do you make that happen
