High-Precision Radar Frame & Antenna Structure Fabrication | Questaero Systems
Radar Structure Manufacturing in India plays a critical role in strengthening the nation’s defence capabilities through precision engineering, advanced fabrication, and strict quality control. At Questaero Systems, we deliver mission-critical radar mechanical structures, antenna back frames, pedestal assemblies, and structural integrations for ground-based and mobile defence radar systems.
As India accelerates indigenous radar development under Make in India and Atmanirbhar Bharat initiatives, reliable mechanical manufacturing partners are essential. Our integrated fabrication and machining capabilities support radar OEMs, defence integrators, and government programs with high-rigidity, alignment-critical structural assemblies.
What is Defence Radar Mechanical Structure Manufacturing?
Defence radar mechanical structure manufacturing involves the design, fabrication, machining, assembly, and inspection of load-bearing frameworks that support radar antennas and associated subsystems.
These structures must:
- Maintain precise antenna alignment
- Resist wind and dynamic rotational loads
- Minimize deflection and vibration
- Support motorized scanning systems
- Protect sensitive electronics
- Withstand harsh field environments
Even minimal misalignment can affect beam steering and tracking accuracy. That is why radar mechanical fabrication demands aerospace-level precision.
Our Core Capabilities in Radar Mechanical Structure Manufacturing
1. Radar Antenna Back Structure Fabrication
We manufacture:
- Truss-based antenna back frames
- AESA radar mounting structures
- Rectangular and circular radar frames
- High-stiffness structural supports
These are engineered for:
- Torsional rigidity
- Load distribution efficiency
- Weight optimization
- Long operational life
2. Radar Pedestal & Rotating Assembly Structures
Radar systems require precise integration between the antenna frame and rotating drive systems. We manufacture:
- Bearing housing structures
- Gearbox interface frames
- Motor base mounting plates
- Precision-aligned rotational assemblies
Critical interfaces are CNC machined to maintain flatness, perpendicularity, and parallelism.
3. Precision CNC Machining for Critical Interfaces
In defence radar mechanical structure manufacturing, the most critical surfaces include:
- Bearing seats
- Gearbox mounting interfaces
- Antenna alignment planes
- Motor base interfaces
Our multi-axis CNC machining ensures tight tolerance control and geometric accuracy essential for radar performance.
4. Controlled Welding & Distortion Management
Large radar structures involve heavy structural welding. Our approach includes:
- Jig-based welding setups
- Controlled heat sequencing
- Weld distortion monitoring
- Post-weld dimensional verification
Distortion control is critical to maintaining structural alignment and mechanical stability.
5. Surface Treatment & Defence-Grade Coating
Radar structures operate in coastal, desert, and high-humidity environments. We provide:
- Surface preparation and blasting
- Epoxy primer application
- Military-grade top coating
- Controlled dry film thickness (DFT) inspection
This ensures corrosion resistance and long-term durability.
Engineering Considerations in Radar Structure Manufacturing
