32dBi Marine Slotted Waveguide Array

X Band Slotted Waveguide Array Antenna for Marine Navigation Radar

This product is a professional Array Antenna featuring a slotted waveguide array design for X band marine navigation radar. The antenna operates from 9.38GHz to 9.44GHz, which is the standard法定频段 for maritime radar worldwide. As a Slotted Waveguide Array, it offers very high gain, extremely narrow horizontal beamwidth, and low side lobe levels. The antenna provides horizontal polarization, which is optimal for sea surface propagation. It is built from aluminum with conductive oxidation treatment for marine corrosion resistance. This antenna is the standard choice for ship navigation radar systems.

This slotted waveguide array delivers excellent electrical performance at X band. The Voltage Standing Wave Ratio (VSWR) is rated at 1.2, which shows very good impedance matching and low signal loss. The gain is 32dBi or higher, providing strong signal聚束 for long distance target detection. The horizontal beamwidth is 0.7 degrees or less, giving very high azimuth resolution to distinguish between close targets like multiple ships, buoys, and rocks. The horizontal side lobe level is very low, which strongly suppresses sea clutter and environmental interference to reduce false alarms. The vertical beamwidth is matched for sea surface detection.

One clear strength of this Slotted Waveguide Array is its excellent performance in marine environments. It is widely used for ship navigation, maritime law enforcement, port and waterway control, offshore platforms, fishing operations, inland waterway shipping, maritime emergency response, and ocean weather observation. The low side lobe design keeps radar images clean and clear. The horizontal polarization works best for detecting ships, buoys, and shore targets over water. The corrosion resistant aluminum construction withstands salt spray, sea wind, and temperature extremes.

In practical use, this Array Antenna handles marine navigation tasks very well. For ship navigation, it provides reliable target detection and collision avoidance in rain, fog, night, and rough seas. The narrow beam and low side lobes allow accurate positioning of nearby vessels and obstacles. The rugged construction survives vessel pitching and rolling in heavy seas. It stands as a solid example of a well designed slotted waveguide array for X band marine navigation radar applications from 9.38GHz to 9.44GHz.
