PAMS Airborne Instrumentation.
Abstract
This Final Report documents the design, development, fabrication, and testing of the Airborne Signal Sources and the Attitude Monitoring System (AMS), which serve as complementary airborne test instrumentation for the Precision Antenna Measurement System (PAMS). The PAMS, which is described in RADC-TR-73-233 (AD-915 581), is a dynamic passive measurement system designed to measure and analyze twelve (12) airborne microwave signals in the 0.1 - 18.0 GHz frequency range simultaneously. The Airborne Signal Sources, described in Part 1 of this report, provide a set of stable RF signals (0.2 - 18.0 GHz) which are used to illuminate the airborne antennas being evaluated and measured by PAMS. The aircraft Attitude Monitoring System (AMS), described in Part 2 of this report, monitors and records the attitude of the aircraft during the flight test. The time correlated attitude data is merged with data collected by PAMS, to provide accurate heading, roll, and pitch information for the resulting antenna pattern. Part 3 of this report is an analytical study of accumulative dynamic errors of the Precision Antenna Measurement System operating with the Airborne Signal Sources and the Attitude Monitoring System. The errors, which have been identified by the study, will be validated by a measurement program during FY-75. Part 3, as well, includes a flight profile study which defines optimum flight patterns for antenna evaluations.
