摘要

Two-dimensional mappings of an aircraft landing gear noise was obtained from fly-over measuring by using array signal processing technology,with multi-arms spiral array, the results show:the aircraft landing gear noise is broadband with some single tones,and is concentrated in 1000Hz below,the noise source was analyzed,supporting landing gear noise reducing design.
