FRP radar Radome Satellite Positioning Monitoring Antenna Beautification Protective Shell White Hand Paste Cover Customization
Fiberglass radar domes are high-performance protective solutions widely deployed in aerospace, military radar, communication base stations, and other critical sectors. Constructed from fiberglass-reinforced resin-based composite materials, these domes embody a suite of exceptional properties and deliver extensive application potential.
Product Features
The defining characteristic of fiberglass radar domes lies in their superior radar wave transmission capability, ensuring unimpeded signal integrity. With a dielectric constant ranging from 2.6 to 4.2, round-trip radio frequency loss is ≤0.5 dB, and wave transmission efficiency exceeds 95%. Beyond shielding radar antennas from environmental elements—including wind, rain, snow, dust, marine corrosion, and solar radiation—these domes guarantee reliable antenna system operation under all-weather conditions.
Material Advantages
Fiberglass composites offer a distinct advantage in lightweight strength, reducing dome mass while enhancing the performance of aircraft and other mobile platforms. Their exceptional weather resistance enables operational stability across a wide temperature range (-40°C to +70°C). Additionally, these domes exhibit minimal color fading under prolonged sunlight exposure over three years and demonstrate high resilience to marine atmospheric corrosion.
Manufacturing Processes
Production of fiberglass radar domes employs advanced techniques such as hand lay-up, vacuum bagging, compression molding, autoclaving, filament winding, and Resin Transfer Molding (RTM). These methods accommodate complex geometries, ensuring precision engineering and consistent quality. A common design feature is the sandwich structure, comprising two outer fiberglass panels and a core material, which optimizes lightweight design, strength, and rigidity.
Application Fields
- Aerospace: Protects radar antennas on aircraft, missiles, and other airborne vehicles.
- Military: Withstands extreme environmental conditions to ensure robust radar system functionality.
- Telecommunications: Safeguards antenna systems in communication base stations from external environmental stresses.
Performance Metrics
Key performance indicators include:
- Wind resistance: Capabilities ranging from 45 to 80 m/s (depending on model).
- Humidity tolerance: Operational viability in 0%–100% relative humidity environments.
- Service life: Designed for 15–20 years of reliable performance.
Customization Services
Fiberglass radar domes are engineered to meet client-specific requirements, including electrical specifications and operational conditions. Manufacturers can design NOMEX honeycomb sandwich structures, PMI foam core configurations, or single-wall fiberglass dome bodies tailored to specific antenna frequency bands, addressing the diverse needs of global clients.
With their robust performance and versatile applications, fiberglass radar domes have become indispensable components in modern radar systems, driving innovation across industries reliant on uninterrupted signal transmission and environmental protection.
