Security & Surveillance Radars

DeTect’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 more sensitive, lower cost radar systems on the market today for a wide range security and surveillance applications.

DeTect’s HARRIER line of radars can be used for airspace and marine security applications to monitor a 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:

  • Airspace monitoring & surveillance
  • Aircraft detection & tracking
  • Public event drone & small UAV detection & defense
  • Ground based sense-and-avoid (GBSAA)
  • Marine and coastal surveillance
  • Beyond Visual Line-of-Sight (BVLOS) operation support
  • Airspace sense-and-avoid
  • Border intrusion detection
  • Ultralight, UAV & drone interdiction
  • Obstruction lighting activation
  • Perimeter air & marine security
  • Shoreline & coastal protection

For drone detection, the DroneWatcher Drone Surveillance Radar (DroneWatcher DSR) configuration of HARRIER provides detection of both cooperative and non-cooperative drones with detection ranges for small class drones (Phantom class) to 2+ nautical miles with automatic classification and rejection of false positive targets from similarly sized, non-drone targets such as birds. The DroneWatcher DSR can also be integrated with DeTect’s DroneWatcher RF sensors and with third party video, acoustic and other systems to provide the more comprehensive level of protection and interdiction for drones and small UAVs available on the market.

DeTect’s DroneWatcher drone/small UAV (sUAV) detection and defense solution consists of four primary sensor technologies that can operate independently or together to provide complete, multi-layer security that meets the risk management and budget objectives of each customer:

DroneWatcherAPP – uses advanced signals intelligence technology to turn an Android smartphone or tablet into a drone and small UAV detector that detects, tracks and records information on about 90% of non-encrypted consumer drones with a range of up to 1/3-1/2 mile. The APP also records data including the drone type, ID and other information that can be used to document incursions and support apprehension and prosecution by local law enforcement. Multiple devices using the DroneWatcher APP Pro version (paid) in an area can be grouped to provide a wide area drone surveillance mesh network with an optional consolidated situational awareness secure web display and automatic visual, audible and text message alerting. The free and Pro versions of the DroneWatcher APP are available on Google Play and on the Amazon appstore.

DroneWatcherRF Mini – a low-cost compact mini-Android computer running DroneWatcher APP Pro as a fixed base drone surveillance node for personal home privacy protection or business security with an extended detection range up to one mile. Multiple DroneWatcherRF Mini devices can be grouped to provide a wide area drone surveillance mesh network with a consolidated situational awareness secure web display and automatic visual, audible and text message alerting.

DroneWatcherRF – monitors the radio frequency spectrum to identify known drone and suspected signatures. DroneWatcherRF is able to detect over 98% 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 also continually being added to DeTect’s DroneWatcherRF identification database. DroneWatcherRF also includes DeTect’s proprietary cyber drone interdiction and interception functionality.

DroneWatcher DSR (drone surveillance radar) – primary radar designed specifically for small, low flying, non-cooperative targets in high clutter environments. DSR is able to detect and track consumer, prosumer and military cooperative and non-cooperative drones within line of sight and at longer ranges out to 2+ miles. The DroneWatcher DSR detects and tracks programmed drones on autopilot that are not detectable by DroneWatcher APP and RF. The DSR also includes DeTect’s proprietary drone interdiction and inception functionality.


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:

  • Commercial & civil aviation airports
  • Public, concerts, sporting & race events
  • Military airfields & ranges
  • Rocket launch complexes
  • UAV & UAS operation support
  • Obstruction lighting activation
  • Government installations
  • Industrial plants, refineries & power plants
  • Ports, waterways & coastlines
  • Borders High security facilities
  • Wind farm gap filler

Interoperability & Integrated Technology

HARRIER security & surveillance radars are fully remotely controllable and viewable. HARRIER 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 integration 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.
