Dimensional Control Engineering FOR ANTENNAS
AND RADAR SYSTEMS:
SUB-MILLIMETER ACCURACY
Ensure maximum efficiency in signal transmission, reception, and tracking with advanced photogrammetry and laser tracker solutions.
THE CHALLENGE OF LARGE STRUCTURES
Defense radar systems, aerospace antennas, and radio telescopes operate at the limits of physics. Any millimeter-scale deviation caused by imprecise assembly, wind, or thermal deformation can have serious consequences: - Drastic loss of signal gain; - Excessive noise in communications; - Critical failures in target tracking. Traditional measurement methods cannot accurately solve this problem
Critical Solutions and Applications
Large-Volume Metrology
We use large-volume metrology systems to calibrate massive pieces of equipment in their actual operating positions.
We provide the precise mathematical models your engineering team needs to recalibrate the structure and restore 100% of its radio frequency (RF) efficiency.
Inspection and Calibration of Reflective Surfaces
RMS Calculation (Parabolic Profile):
High-density measurement to calculate the deviation from the perfect parabola, ensuring the signal is properly focused.
Panel Fine-Tuning (Panel Setting):
Real-time guidance for panel alignment, ensuring continuous curvature without steps.
Deformation Analysis:
3D mapping at different temperatures and angles (gravity) to apply direct compensations in the control software.
Structural Alignment
Azimuth and Elevation Axes:
Determination of orthogonality to eliminate mechanical pointing errors.
Rails and Bearing Paths:
Inspection of flatness and circularity in rotating antennas to prevent wear and vibration.
Focal Assembly Positioning:
Precise geometric alignment of the sub-reflector and feed with the optical center of the dish.
Precision That Guarantees Results
Prevent mechanical misalignments and gravity-induced deformations from compromising your telecommunications or defense system.
WHAT SETS US APART IN THE FIELD
Measuring antennas requires working in hard-to-reach locations, such as tall towers and building rooftops. We overcame this by combining dynamic photogrammetry and a laser tracker:
"Frozen" Measurement
We captured the giant structure almost instantly, before gusts of wind or thermal changes could alter it.
Practical Adjustment Guide
Instead of simply providing a report of errors, we provide an action plan (specifying which tensioners/screws to adjust and by how many millimeters), allowing your team to optimize the antenna in the shortest possible time.
Best-Fit Analysis:
We process the data to intelligently find the optimal paraboloid.
