Calibration and Clutter Cancellation Techniques for Accurate Wideband Radar Cross Section Measurements
(2021-05-14)The expected received power is a key design parameter when designing a radar system. The radar’s receiver must be sensitive enough to detect the object of interest without being saturated by the highest received power. The ... -
Calibration of a Handheld X-Ray Fluorescence Device to Detect Chemical Stabilizers in Soil Subgrades
(2018-12)Chemically stabilized subgrades increase the overall quality of pavements compared to non-treated subgrades. Currently, there is no efficient way to detect chemical stabilizers (CS) in pavement subgrades. Generally, only ... -
Oklahoma Department of Transportation sprayer equipment assessment & calibration workshops (FHWA-OK-09-08)
(2009-12)Oklahoma State University (OSU) Roadside Vegetation Management (RVM) Program personnel assessed and inventoried 82 ODOT herbicide spray units. At these workshops, 259 ODOT herbicide applicators were trained in sprayer ... -
TECHNIQUES AND INSTRUMENTATION FOR PHASED ARRAY CALIBRATION
(2020-05-08)Active phased arrays suffer the inherent problem of excitation errors, i.e., incorrect phase and amplitude excitation of the antenna elements. Excitation errors degrade critical performance parameters since they increase ... -
Uncertainty Analysis for In-situ Fan Curve Calibration in Variable Air Volume Systems
(2016-12-16)In order to obtain in-situ fan performance curves for variable air volume (VAV) air handling units (AHUs) with predicted uncertainties, airflow measurements for an extended time and a tailored calibration procedure were ...
