The radar antenna in marine navigation consists of a rotating scanner that emits and receives radio waves. Key parts include the reflector, feed horn, and motor assembly for rotation. It is mounted high on the ship to ensure optimal detection range and accuracy.

Size: Varies by model; typically 1-5 meters in diameter for marine radar antennas.

Grade: Marine-grade materials, often compliant with IEC 60945 or MIL-STD-810 standards.

Viscosity: Not applicable to solid radar antenna parts; relevant only for lubricants (e.g., ISO VG 32-68).

Buoyancy: N/A for fixed antennas; buoyant materials (e.g., closed-cell foam) may be used in floating radar reflectors.

Material: Aluminum, fiberglass, or stainless steel for corrosion resistance; radomes often use polycarbonate or fiberglass.

Frequency Range: Typically X-band (8-12 GHz) or S-band (2-4 GHz) for marine radar systems.

Power Handling: 1-50 kW, depending on application and radar class.

Beamwidth: 0.5°-5° azimuth, 15°-30° elevation for directional antennas.

Polarization: Horizontal or circular for marine navigation radar.

Mounting: Pole, mast, or gyro-stabilized platforms; IP66/IP67 waterproof ratings.

Weight: 10-200 kg, depending on size and materials.

Operating Temperature: -30°C to +70°C for standard marine environments.

Radar Antenna Parts and Marine Navigation products typically comply with maritime standards such as IEC 60945, IEC 62388, and IMO SOLAS regulations. For specific compliance details, please refer to the product documentation or manufacturer specifications.
