Innovative Antenna Chamber Characterization

摘要

This paper describes an innovative test approach to validate an anechoic Compact Range antenna indoor chamber. It documents the antenna chamber mmW characterization efforts and results for the Lockheed Martin Mission Systems & Training (MST) antenna chamber CR1 in Owego NY. The mmW characterization results indicate that the chamber amplitude performance is better than 0.8 dB RMS, and the chamber phase performance is better than 5 degree RMS. These errors are reasonably small compared with typical Electronic Support Measure (ESM) antenna calibration residual errors. Based on these characterization results, it is concluded that the Owego chamber CR1 is sufficient for mmW ESM antenna calibrations.
