Performance Evaluation of Velocity Measurement Systems

Abstract

Performance evaluations of velocity measurement systems from 6 manufacturers were made at this research facility (CERF). These systems, which consisted of both linear and pendulous transducers and associated signal conditioners were tested on the CERF drop tower for dynamic inputs to the vertical systems and on the CERF sled track for dynamic inputs to the horizontal systems. Dynamic transducer inputs were used to obtain data for evaluating upper frequency limits, accuracy, risetime capabilities, long-line effects, and on-axis and cross-axis shock survivability. External carrier- demodulator signal conditioners which were compatible with the DX-type pendulous transducers were also tested and evaluated for rise-time capability, high- frequency capability, overshoot, ringing, noise, and long-line performance effects. After individual evaluations were made on each system, an overall evaluation was made. One transducer was determined to be best suited for most AFWL field measurements.
