Key Parameters Tested in Radome Positioners
Impact: Directly affects the radar’s tracking accuracy (i.e., how precisely the radar can determine the location of a target).
Impact: Directly affects the radar’s maximum detection range. Lower efficiency means less signal is transmitted and less is received.
Impact: Increased side lobes can make the radar susceptible to jamming or cause it to detect energy from unwanted directions.

A radome test gimbal positioner is a precision positioning system used to rotate and position radomes and antenna assemblies during RF and antenna measurement tests.
It is used to evaluate how a radome affects antenna performance, including boresight error, transmission efficiency, and radiation pattern distortion.
The system provides three-axis control, including Azimuth (AZ), Elevation (EL), and Roll, enabling comprehensive angular testing of radome and antenna systems.
Boresight error is the difference between the mechanical pointing direction and the actual electrical direction of the transmitted antenna beam. It can directly affect radar tracking accuracy.
Transmission efficiency is measured by comparing the received signal power with the radome installed against a reference measurement taken without the radome.
Yes. The positioner can sweep the radome and antenna assembly through the required angular range to help measure and analyze radiation pattern distortion, including changes to sidelobe performance.
The system specifications include a driving accuracy of 0.08° RMS with load and high-resolution encoders for precise radome and antenna positioning.
The radome positioner can support a maximum load of up to 30 kg, depending on the system configuration.
When integrated with the DMC 360 software and an appropriate test configuration, the gimbal system supports high-fidelity testing at frequencies up to 110 GHz.
Yes. The system can be configured based on application requirements, including radome size, load capacity, angular movement, positioning accuracy, and antenna measurement requirements.
