Precise and Portable Antenna Test System (PAPATS)

Summary

The Naval Surface Warfare Center, Crane Division (NSWC Crane) has developed, built, and patented the precise and portable antenna test system (PAPATS), which can be set up in the actual field environments where an antenna system would be deployed. PAPATS employs near-field techniques in a manner that can quickly and accurately measure far-field signal patterns. The device consists of a computer, a robotic positioner, a probe, and the antenna under test (AUT). The robot can move the probe, the AUT, or both over the desired test surface. Additionally, either the probe or the AUT can transmit while the other receives.

Technology Benefits

Precise - Indoor positional accuracy in a portable outdoor unit. IMU provides pointing accuracy within 1/2 degree and RTK GPS provides location accuracy of 1 cm horizontally and 2 cm verticallyPortable - Can be set up outdoors in a variety of field environments in order to assess the impacts of varied ground materials on antenna patternsEfficient - Thoroughly determine far-field antenna patterns and polarization measurements for high frequency antennas in a small test range space

Technology Application

Any outdoor application that requires indoor positional accuracyFar-field testing environments Remote applications that require portable test equipment
