Abstract

The National Institute of Standards and Technology (NIST) Communication Technology Laboratory (CTL) developed the Synthetic Aperture Measurement with Uncertainties and Angle of Arrival (SAMURAI) millimeter-wave testbed and technique. SAMURAI utilizes a synthetic aperture method using a robotic arm and vector network analyzer/large signal network analyzer (VNA/LSNA) for flexible and accurate propagation channel and device measurements as a function of both frequency and angle. Note: this technique can use a measurement tool. In the NIST configuration of SAMURAI, linear and non-linear measurements are possible leveraging the large signal network LSNA measurement capability. We perform wideband measurements from 26.5 to 40 GHz on an optical table in a controlled laboratory to ensure stability during our measurements. The robotic arm allows for multiple configuration scan types from rectangular to cylindrical. In this documentation, we provide a getting started documentation, software for both data acquisition and data analysis. We also provide past measurement campaigns data from an Angle-of-Arrival measurements to the Central Utility Plant measurements. Finally, we provide base software libraries and frequently asked questions.
