Reducing Uncertainty with Calibration for Angle of Arrival Testing

Webinar Overview

EW receivers often use angle of arrival (AoA) as a primary sorting parameter in dense signal environments. Reducing the uncertainty in direction-finding (DF) receiver measurements leads to better accuracy in AoA estimation. Prior to AoA accuracy testing in a lab setting, calibration -- process, application and verification -- can be performed at the interface to the system under test. This webcast examines three measurement receivers that enable effective calibration: power meters, oscilloscopes, and vector network analyzers. These are used to measure uncertainty in amplitude offset, phase offset, and time skew. With that data, closed-form expressions of the total uncertainty can be derived according to the current ISO Guide to the Expression of Uncertainty in Measurements.
