Description

Technical Field

[0002] Compact range measurement technology was developed to address the challenges of alignment, poor confidentiality, and demanding climatic conditions encountered in outdoor far-field measurements. Specifically, it enables far-field measurements of antenna parameters or radar target scattering characteristics at close range.

This allows the system to obtain far-field data without leaving the target or the antenna's far field. However, existing conventional compact range measurement systems maintain a consistent measurement environment consistent with the surrounding natural environment, making it difficult to measure data in diverse environments. Consequently, the data that can be measured is limited and incomplete. Utility Model Content
