Gimbal Positioner
DMC Gimbal Positionerdelivers the uncompromising mechanical accuracy required for next-generation radome and antenna measurement. Featuring high-resolution encoders and three mutually orthogonal axes (Azimuth, Elevation, and Roll), our gimbal precisely simulates real-world flight conditions to quantify boresight error, transmission efficiency, and pattern distortion. When integrated with DMC 360 Software, it ensures fast, reliable, and high-fidelity testing up to 110 GHz, transforming your test range into a precision diagnostic facility.
Key Features to Highlight:
3-Axis Control: Azimuth, Elevation, and Roll for comprehensive coverage.
High Accuracy: Resolution down to 0.025 (per the DMCRF spec sheet).
Integrated Software: Seamless operation with DMC 360 Software for advanced analysis.
Application: Ideal for high-fidelity testing of radome and antenna system

RADOME AUT POSITIONER
Key Parameters Tested in Radome Positioners
- Bore Sight Error: The positioner rotates the radome/antenna assembly in Azimuth (AZ) and Elevation (EL), and the test equipment measures the difference between the true mechanical pointing angle and the actual electrical angle of the transmitted beam.
Impact: Directly affects the radar’s tracking accuracy (i.e., how precisely the radar can determine the location of a target).
- Transmission Efficiency: The test system measures the received signal power with the radome in place and compares it to the power received without the radome (the reference measurement).
Impact: Directly affects the radar’s maximum detection range. Lower efficiency means less signal is transmitted and less is received.
- Pattern Distortion:The positioner sweeps the radome/antenna assembly across the desired angular range, and the test equipment maps the full 3D radiation pattern, focusing on the strength of the side lobes relative to the main beam.
Impact: Increased side lobes can make the radar susceptible to jamming or cause it to detect energy from unwanted directions.
