Webinar Overview

In this short presentation, we discuss calibration and uncertainty for angle-of-arrival (AoA) simulation using RF signal generators. After reviewing the three dominant types of direction finding (DF) used in radar warning receivers (RWRs), we explain how to calibrate for AoA according to each DF method. For phase AoA calibration, we show how the vector network analyzer is the ideal test instrument and explain the three contributors to uncertainty in phase AoA simulation: systemic error, random error and drift. Finally, we discuss how to scale the calibration solution for RWRs with higher port counts and distributed apertures.
