A New Testing Method for High-frequency Power Wave Trapper Measurement Based on Correlation Theory

摘要

The composing of high-frequency power wave trapper were introduced in this article, and a new method based on traditional correlation theory is presented in the test system. Cross-correlation functions of the two measured signals are directly computed and some properties about correlation and sine function are adopted to separate the part noise and useful signal, so the measurement accuracy are improved. The Matlab is adopted in the typical model bandwidth power wave trapper coil circuit to calculate and to simulate, and the validity and the accuracy of this method are discussed. The conclusions are supported by the results. Primary chart of systemic configurable design is drawn as a model to make apparatuses for wave trapper measurement.
