Low Altitude Multidimensional Defense System in Key Areas
Introducing our state-of-the-art Low Altitude Defense System, expertly crafted for safeguarding key areas with a sophisticated blend of cutting-edge technologies. This comprehensive package includes surveillance radar, passive radio detection tools, multispectral electro-optical cameras, fixed unmanned jamming aircraft, and handheld jamming guns, all anchored by advanced data acquisition and processing centers. Designed for ease of installation and quick dismantling, it offers unmatched flexibility for deployment. The system meticulously defines warning, alarm, and no-fly zones within its broad detection spectrum, integrating advanced detection technologies for peerless real-time monitoring across multiple frequency bands. Enjoying omnidirectional coverage with zero blind spots, it provides a holistic defense solution. As an impregnable shield, it prevents the incursion of unmanned aerial vehicles, powered parachutes, gliders, and helicopters into sensitive zones such as airports, oil fields, storage areas, borders, nuclear sites, bridges, dams, crucial government facilities, major conference locations, and other critical infrastructures.

The NH-104 Our NH-104 three-coordinate early warning radar stands as a beacon of innovation, engineered for the precise surveillance of low altitude small targets. It integrates advanced radar technologies, including fully coherent pulse Doppler processing, microstrip patch array antennas, digital beamforming in elevation, simultaneous multi-beam reception, single pulse angle measurement, and tracking while scan (TWS) capabilities. These cutting-edge features enable dynamic phase scanning across azimuth and elevation, ensuring comprehensive coverage. The radar is distinguished by its rapid beam scheduling, extraordinary data rate, excellent angle resolution, and precise height measurement. This versatile radar system excels in air surveillance for essential regions such as border defense, coastal security, oil and gas exploration sites, storage facilities, bridges, reservoirs, nuclear power stations, and other crucial setups.
