HARRIER Air Surveillance Radar for border securityDeTect's radar processing technology developed specifically for reliable detection and tracking of small, non-cooperative, low radar-cross section, non-linearly moving targets make it one of the most sensitive, low cost radar systems on the market today for security and surveillance applications. DeTect's HARRIER line of radars can be used for airspace and marine security applications to monitor a wide range of targets including aircraft, ultralights, drones, unmanned aerial vehicles (UAV) and systems (UAS), helicopters, ships, and boats. HARRIER provides full, multi-functional surveillance coverage from ground level to altitudes above 20,000 feet AGL with simultaneous air and marine target detection, tracking and automatic intrusion alerting. HARRIER is an ideal, cost-effective solution for many force protection and homeland and industrial security applications. HARRIER shares a common platform with DeTect's MERLIN system that was designed specifically for detection and tracking of small radar cross section (RCS) targets in high clutter environments, and offers the highest level of performance available for detection, tracking and identification of drones and small UAVs.

HARRIER applications include:

For drone detection, the HARRIER Drone Surveillance Radar (HARRIER DSR) configuration provide detection of both cooperative and non-cooperative drones with detection ranges for micro class drones to 2+ miles with automatic classification and rejection of false positive targets from similarly sized, non-drone bird targets. The HARRIER DSR can also be integrated with DeTect's DroneWatcher System to provide the most comprehensive level of protection and interdiction for drones and small UAVs available on the market.

DroneWatcher consists of two sensors: DroneWatcherAPP, an Android application available on Google Play or app that makes Android smartphones and tablets into drone detectors, and DroneWatcherRF, a radiofrequency scanner that detects, tracks, IDs and interdicts drones. DroneWatcherAPP detects, tracks, alerts and records information on 95% of commercially available consumer and prosumer drones using advanced signals intelligence technology developed by Panama City based DeTect. The app alerts the user when a drone is detected within 1/4 to 1/2 mile recording the drone type and ID which can be used to document incursions and support apprehension and prosecution by local law enforcement if needed. Multiple APP users can be combined using DeTect's DroneWatcherWEB service to create a crowd sourced network of wide area coverage. DroneWatcherRF monitors the radio frequency spectrum to identify known drone signatures and is able to detect over 95% of the commercially-available, consumer and prosumer drones on the market out to 1-2 miles providing detailed information including drone type, ID and other data. New signatures are continually being added to DeTect's DroneWatcherRF identification database. DroneWatcherRF also includes DeTect's proprietary drone interdiction and interception functionality (more information).


HARRIER Drone Surveillance Radar mobile display showing drone tarcks and probable launch/control sitesSystems are offered in various base configurations that include the HARRIER Airspace Surveillance Radar (ASR) and the Marine Surveillance Radar (MSR). With multiple parallel processors, the radar can operate as a multi-function system providing ASR and MSR functionality from a single radar sensor or network of sensors, and as noted above, HARRIER is fully compatible and can be integrated with the DroneWatcher technology. All HARRIER systems use state-of-the-art solid-state Doppler radar technology developed by DeTect specifically for detection of low RCS targets in high clutter environments in target optimized S-band, X-band and combined S/X-band radar frequencies. DeTect's solid-state radar technology offers significant increased performance, longer useful life and lower maintenance costs over conventional magnetron-based systems.

HARRIER applications include a wide range of sites, types, sizes and configurations from single facilities to large-area or linear radar networks for force protection and facility security, including:

Interoperability & Integrated Technology:

HARRIER security & surveillance radars are fully remotely controllable and viewableHARRIER systems can operate as a stand alone security/ force protection radar system detecting and alerting perimeter intrusions by air and water. The system can be programmed to detect intruders (ships, boats, aircraft, ultralights, UAVs) crossing pre-set site perimeters or entering restricted zones, providing automated visual and audible notifications to security forces by text message, pager or cellular phone and direct read-out at remote monitoring stations. HARRIER ASR systems can also be used as a gap filler radar to fill in data for navigation and military surveillance radars in areas blocked by terrain or structures such as wind turbines.

HARRIER inlcudes a SDK for intergration with third party sensorsHARRIER radars use high speed scanning for enhanced small target detection in high clutter environments such as developed areas, terrain and high sea states. Systems are optimized for detection of small targets that includes small motorized high-speed watercraft, floating objects, low flying aircraft and ultralights. Automatic detection and tracking includes user-defined monitoring and alarm zones. Systems are offered in fixed skid and mobile configurations and can be linearly networked to cover large areas and lines such as border crossings, coastlines and large facilities. DeTect's technology is highly customizable providing radar, video, and thermal detection and acoustic deterrent through a single user interface display with advanced alerting and response features all viewable and controllable remotely in real-time. HARRIER features include:
