LDV 스펙트럼 분석을 위한 재생방법의 비교 연구
A Comparative Study of Reconstruction Methods for LDV Spectral Analysis
초록
A critical evaluation is made of the spectral bias which occurs in the use of a laser doppler velocimeter(LDV). Two processing algorithms are considered for spectral estimates: the sample and hold interpolation method(SH) and the nonuniform Shannon reconstruction technique(SR). Assessment is made of these for varying data densities
