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 systems, 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 detection, tracking and 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:


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. 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 (vehicles, ships, boats, aircraft, ultralights, UAVs) crossing a pre-set site perimeters or zones, providing automated visual and audible notifications to security forces by text message, pager or cellular phone or direct read-out at remote monitoring stations. HARRIER ASR systems can also be used as a gap filler radar provide data for navigation and military surveillance radars in areas blocked by terrain or structures including wind turbine farms.

HARRIER inlcudes a SDK for intergration with third party sensorsHARRIER radars are 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:

Visual Warning Systems:

HARRIER Visual Warning System for transmission line abstruction lighting activationIn response to the Dark Sky initiative to reduce light pollution and customer demand, DeTect developed the HARRIER Visual Warning System automatic obstruction lighting activation system. The system provides continuous 360 degree radar surveillance of the airspace around a wind farms, communications towers, power lines and installations that require aircraft obstruction lighting from the ground level to above aircraft flight altitudes, automatically issuing warnings to activate obstruction lighting when aircraft are detected at a defined outer perimeter. HARRIER is the most capable technology for available and meets or exceeds all regulatory requirements including the pending US FAA and Canadian NAVCAN requirements and well as various EU standards. The HARRIER VWS additionally is compatible with all wind energy turbines, control and communication networks, and obstruction lighting systems.

The HARRIER VWS is a highly customizable for each site and application with multiple alert zones and activation perimeters, and is available as stand-alone system or integrated with other sensors and warning devices such as audible beacons. The design incorporates redundant sensors and back-up detectors that include TCAS and ADSB receivers for a greater safety and reliability margin. With DeTect's MERLIN processor add-on, a HARRIER VWS can additionally provide VWS and bird radar functionality from a common sensor platform.

HARRIER VWS advantages include:
